7.5   Self Orthogonal Latin Squares (7 x 7)

A Self Orthogonal Latin Square A is a Latin Square that is Orthogonal to its Transposed T(A). The transposed square T(A) can be obtained by exchanging the rows and columns of A.

If the main diagonal contains the integers {ai, i = 1 ... 7} in natural order, the Self Orthogonal Latin Square is called Idempotent.

7.5.1 Simple Magic Squares

A construction example of a Simple Magic Square M = A + 7 * T(A) + [1] is shown below:

4 6 2 1 0 5 3

Each Self Orthogonal Latin Diagonal Square corresponds with 7! = 5040 Self Orthogonal Latin Diagonal Squares, which can be obtained by permutation of the integers {ai, i = 1 ... 7}.

A Base of 64 Idempotent Squares has been found in Section 7.5.3 below. The total number of Self Orthogonal Latin Diagonal Squares will be 64 * 5040 = 322560, which can be generated quite fast with routine SelfOrth7c.

In addition to the transformations and permutations described above, each Self Orthogonal Latin Diagonal Square A corresponds with 24 transformations, as described below.

  • Any line n can be interchanged with line (8 - n). The possible number of transformations is 23 = 8
    It should be noted that for each square the 180o rotated aspect is included in this collection.

  • Any permutation can be applied to the lines 1, 2, 3 provided that the same permutation is applied to the lines 7, 6, 5. The possible number of transformations is 3! = 6.

The resulting number of transformations, excluding the 180o rotated aspects, is 8/2 * 6 = 24, which are shown in Attachment 7.5.12

Attachment 7.6.31 illustrates the construction of an order 28 Composed Pan Magic Square based on the Self Orthogonal Composed Pan Magic Latin Square shown above.

7.7   Composed Latin Squares (29 x 29)

Order 7 Self orthogonal Latin Diagonal Squares can be used to construct order 29 Self Orthogonal Composed Latin Diagonal Squares.

The required order 7 Self orthogonal Latin Diagonal Sub Squares can be constructed based on the sub series:

    {0, 1 ... 6}, {7, 8 ... 13}, {14}, {15, 16 ... 21} and {22, 23 ... 28}

with respectively the magic constants s7 = 21, 70, 126 and 175

Attachment 7.8.31 shows the resulting order 35 Composed Ultra Magic Square based on the Self Orthogonal Composed Ultra Magic Latin Square shown above.

7.9   Composed Latin Squares (36 x 36)

Order 7 Self orthogonal Latin Diagonal Squares can be used to construct order 36 Self Orthogonal Composed Latin Diagonal Squares.

The required order 7 Self orthogonal Latin Diagonal Sub Squares can be constructed based on the sub series:

    {0, 1 ... 6}, {7, 8 ... 13}, {14, 15 ... 20}, {21}, {22, 23 ... 28} and {29, 30 ... 35}

with respectively the magic constants s7 = 21, 70, 119, 175 and 224
