1. Organization of words

The organization of words can be divided into (planar) on the same face and (spatial) on different faces.

⑴ The following are on the same face:

1. three letter forms as shown in fig. 7;

2. In the form of four letters as shown in fig. 8;

3. in the form of five letters as shown in fig. 9;

4. in the form of six letters as shown in fig. 10;

5. in the form of seven letters as shown in fig. 11;

6. as shown in fig. 12 in nine letters.

⑵ The following are on different sides:

1. As shown in the square cross-section of fig. 13. In the figures, "1" to "9" correspond to the portions intersecting each face of the cube when one face is truncated. One form of "1" to "9" may be regarded as one body line of the third-order word side. Words with word lengths of one to nine letters can be spelled in this way.

2. The chess elephant walk. The words with four letters and more than four letters can be spelled according to the chess elephant walking method.

3. The method for walking the chess backing horse. The words with four letters and more than four letters can be spliced according to the running method of the chess horse.

2. The number of letters is assigned.

The third-order magic cube has 54 color blocks and can be filled with 54 letters. Firstly, 3 color blocks are reserved, one universal letter is given, 51 color blocks are left, and the left color blocks are distributed to 26 English letters.

The third-order word side letter number distribution scheme is shown in table 1:

TABLE 1

3. Moth-shaped letter

The a person affected with favus on the head letters are denoted by xi and occupy four positions in the third order word, 1 corner block, 2 edge blocks, 1 center block. ζ is the fourteenth greek letter, mathematically representing a random variable. The principle of use a person affected with favus on the head is that it can be used without.

4. And determining the number distribution of each letter on the corner block, the edge block and the center block.

Several proper nouns are introduced: third-order magic cube, color block, corner block, edge block and center block.

1. Three-order magic cube: the three-order large cube is composed of 3×3×3=27 equal-sized small cubes, but in order to achieve the rotation function of the cube, 1 small cube is removed from the interior, and the cube is changed into a structure suitable for rotation. So the third order cube has in fact 27-1=26 small cubes. While these small cubes can be seen on the surface of the large cubes. Three faces can be seen in small cubes on the corners; small cubes on the ribs, two faces can be seen; a small cube in the center can see one face. The facets of these small cubes constitute the surface of the cube that we can see (in the present invention, the surface of the cube).

Each surface of the magic cube is coated with the same color, and six surfaces share six colors.

2. Color block: the three-order magic cube has 3×3=9 small squares on each face, and each such small square is called a color block. The three-order magic cube has 3×3×6=54 color blocks.

3. Corner block: the 8 vertices have 8 small cubes, each of which has three color blocks perpendicular to each other and intersecting at a point (i.e., vertex), and such color blocks are called corner blocks. The three-order magic cube has 3×8=24 corner blocks. The shaded portion shown in fig. 14 is 4 corner blocks on one face.

4. Edge block: the cube has 12 edges, and after removing the small cubes at two end points on each edge of the third-order magic cube, 1 small cube is also provided. This small cube has two color patches perpendicular to each other and intersecting a line (i.e., the edge), called the edge patch. There are 2 rib blocks on one rib. The three-order magic cube has 2×12=24 prism blocks. The hatched portion shown in fig. 15 is 4 prism blocks on one face.

5. Center block: after each corner and edge block is removed, the remaining 1 color block is called the center block. The three-order magic cube has 6 center blocks. The hatched portion shown in fig. 16 is 1 center block on one face.

Color block distribution: corner block: 24, a step of detecting the position of the base; edge block: 24, a step of detecting the position of the base; center block: 6, preparing a base material; and (5) summation: 54.

The English has 26 letters in total, and one a person affected with favus on the head letters is added, so that 27 letters are used in the invention. The number of the corner blocks and the center blocks is 24, so that the corner blocks and the center blocks can not lack certain letters. Thus, there is a need for a smart arrangement based on the character of the letter in the word.

The specific distribution method comprises the following steps:

1. first, 3 positions are allocated to a person affected with favus on the head letters

The a person affected with favus on the head letters occupy three positions: 1 corner block, 1 edge block and 1 center block.

2. Distribution of corner and edge blocks

The number of corner blocks and edge blocks is 24, and the number of letters to be used is 27, so that the number of corner blocks is 3, and the number of edge blocks is 3. What letters should be removed? What rule goes?

Here, three rules are mainly followed: 1. letter frequency; 2. an initial frequency; 3. the letters removed from the corner blocks are different from those removed from the edge blocks.

3. Allocation of center blocks

Center block allocation: e. a, i, s, r and a a person affected with favus on the head letter.

The number assignment of each letter on the corner block, the edge block, the center block is shown in table 2:

TABLE 2

5. According to the organization form of words on the word side and the rotation rule of the word side, the distribution of each letter on the corner block, the edge block and the center block is skillfully designed.

1. Edge block letter arrangement:

Two perpendicular ribs on the same small cube cannot be separated when rotating. Therefore, the letters on the two blocks are not rotated to the same plane. Thus, when two edge block letters are arranged on the same small cube, both the collocation of the two letters themselves and how to realize by other color blocks when the two letters are required to appear on the same surface are considered.

In order to spell as many words as possible, the letters on two mutually perpendicular adjacent edge blocks on the same small cube are arranged as follows:

① . Two vowels are not arranged.

② . The number of the 24 edge blocks is two, two adjacent and vertical pairs, and the total number of the two adjacent and vertical pairs is 12. The number is only allocated 1 letter, and 3 letters are arranged on the edge block: x, q, z, which are not combined with each other into a pair.

③ . The 24 corner blocks are composed of three letters perpendicular to each other and intersecting at one point, wherein the two letters are combined into a pair, and 3 pairs are arranged at one vertex, and the total number of the two letters is 24. The 24 pairs of letter combinations and the 12 pairs of letter combinations on the prism blocks do not have repeated combinations.

④ . The letters combined with a person affected with favus on the head letters must be a total of 2 letters assigned.

The final arrangement of letters on the prism blocks is shown in fig. 17.

2. Corner block letter

The rule of the rotation of the angle block in the magic cube is as follows: one letter on the corner block, by rotation, can appear in all other positions of the corner block. The three corner blocks on the same small cube cannot be separated when rotating. The letters on the three corner blocks are therefore not rotated to a plane.

In order to spell as many words as possible, at one vertex, the three perpendicular to each other and intersecting the letters of a corner block at one point are arranged as follows:

① . Two vowels are not arranged.

② . The 24 corner blocks are composed of three letters perpendicular to each other and intersecting at one point, wherein the two letters are combined into a pair, and 3 pairs are arranged at one vertex, and the total number of the two letters is 24. The 24 pairs of letter combinations and their combination with the 12 pairs of letters on the prism blocks will not have repeated combinations.

③ . The letters combined with a person affected with favus on the head letters must be a total of 2 letters assigned.

The final arrangement of letters on the corner blocks is shown in fig. 18.

3. Center block letter

The final arrangement of letters on the center block is shown in fig. 19.

Thus, the final arrangement of letters of the present invention is shown in FIG. 20.

It should be noted that although the present invention only provides specific embodiments of the third-order cube, the present invention is equally applicable to fourth-order cubes and other order cubes.
