 7.0    Special Cubes, Prime Numbers 7.10   Magic Cubes, Sum of Latin Cubes 7.10.1 Introduction Comparable with Prime Number Magic Squares (ref. Section 14.12), Prime Number Magic Cubes can be constructed based on suitable selected Latin Cubes. 7.10.2 Simple Magic Cubes (4 x 4 x 4) The elements of three Latin Cubes A, B and C, with latin space diagoanls, might result in a Simple Prime Number Magic Cube D with elements di = ai + bi + ci, i = 1 ... 64 as illustrated below:

 The key to possible solutions is to find Correlated Magic Lines {ai, i = 1 ... 4}, {bj, j = 1 ... 4} and {ck, k = 1 ... 4} such that dijk = ai + bj + ck (i,j,k = 1 ... 4) are distinct prime numbers (64 ea). A few of such sets of Correlated Magic Lines are shown in following table:

 Attachment 7.10.2 shows the resulting Prime Number Magic Cubes (8 ea) with the related Magic Sums. Note: It should be noted that, due to the selected Latin Cubes, the Horizontal Planes are magic as well, as shown in the example above. 7.10.3 Related Magic Squares (8 x 8) Based on the Prime Number Magic Cubes, as discussed in Section 7.10.2 above, following 8 x 8 Prime Number Magic Squares can be constructed: Composed Magic Squares, based on the horizontal Magic Planes of subject cubes; Combined Magic Squares, based on an alternative combination of the Correlated Magic Lines, which will be illustrated in Section 7.10.4 below. Attachment 7.10.3 shows the Composed Magic Squares (8 ea) with the related Magic Sums, based on the Magic Cubes enclosed in Attachment 7.10.2. 7.10.4 Combined Magic Squares (8 x 8) An order 4 Magic Square C2 can be constructed based on Diagonal Latin Squares A and B, defined by two of the three Correlated Magic Lines, say {ai, i = 1 ... 4} and {bj, j = 1 ... 4}:

 The resulting square C2 can be combined with 4 ea Diagonal Latin Squares of order 4, based on the third Magic Line {ck, k = 1 ... 4} as shown below:

 Attachment 7.10.4 shows Combined Magic Squares (8 ea) with the related Magic Sums, based on the Magic Cubes enclosed in Attachment 7.10.2. Each square shown corresponds, for a given square C2, with numerous Prime Number Combined Magic Squares (order of magnitude 484 = 5308416).
