14.0    Special Magic Squares, Prime Numbers

14.15   V type ZigZag

When a Magic Square contains repeated wave type patterns (see below) summing to the Magic Sum s1, it is called a V type ZigZag Magic Square.

Top/Bottom
o - o - o
- o - o -
- - - - -
- - - - -
- - - - -
Left/Right
o - - - -
- o - - -
o - - - -
- o - - -
o - - - -


As illustrated above the repetition can be in the directions:

- Top / Bottom with wrap around and reverse
- Left / Right with wrap around and reverse

If one of these options occurs, the Magic Square is referred to as a Two Way V type ZigZag Magic Square.

If both options are applicable, the Magic Square is referred to as a Four Way V type ZigZag Magic Square.
Such squares occur only for orders larger than 5.

14.15.1 Magic Squares (4 x 4)
        Two Way, V type ZigZag

The defining equations for a Two Way (Top/Bottom) V type ZigZag Magic Square of order 4 can be written as:

a(11) =  s1 - a(12) -   a(15) - a(16)
a( 7) = -s1 + a( 8) + 2*a(12) + a(15) + a(16)
a( 4) =  s1 - a( 8) -   a(12) - a(16)
a( 3) =  s1 - a( 8) -   a(12) - a(15)

a(14) = 0.5 * s1 - a(16)        a(9) = 0.5 * s1 - a(11)
a(13) = 0.5 * s1 - a(15)        a(5) = 0.5 * s1 - a( 7)
a(10) = 0.5 * s1 - a(12)        a(2) = 0.5 * s1 - a( 4)
a( 6) = 0.5 * s1 - a( 8)        a(1) = 0.5 * s1 - a( 3)

which illustrate the consequential symmetry (column symmetrical).

Subject equations can be incorporated in a routine to generate Two Way V type ZigZag Magic Squares (ref. ZigZag4).

Attachment 17.01 shows for miscellaneous Magic Sums the first occurring Two Way V type ZigZag Magic Square.

Each square shown corresponds with 384 (96 unique) squares for the applicable Magic Sum and variable values {ai}.

14.15.2 Magic Squares (5 x 5)
        Two Way, V type ZigZag

The defining equations for a Two Way (Top/Bottom) V type ZigZag Magic Square of order 5 can be written as:

a( 1) =  0.6 * s1 - a( 3) - a( 5)
a( 2) =  0.4 * s1 - a( 4)
a( 3) =           2*a(13) - a(23)
a( 4) =    2 * s1 - a(10) + a(13) - a(14) - a(15) - 2 * a(19) - a(20) - a(23) - a(24) - 2 * a(25)
a( 5) =        s1 - a(10) - a(15) - a(20) - a(25)
a( 6) =  0.6 * s1 - a( 8) - a(10)
a( 8) =        s1 - 3 * a(13) - a(18)
a( 7) =  0.4 * s1 - a( 9)
a( 9) =      - s1 + a(10) - a(13) + a(15) + a(19) + a(20) + a(23) + 2 * a(25)
a(12) =  0.4 * s1 - a(14)
a(11) =  0.6 * s1 - a(13) - a(15)
a(17) =  0.4 * s1 - a(19)
a(16) =  0.6 * s1 - a(18) - a(20)
a(22) =  0.4 * s1 - a(24)
a(21) =  0.6 * s1 - a(23) - a(25)

The consequential symmetry (Columns 2 - 4) is worth to be noticed and the reason that Two Way V type ZigZag Magic Squares of the fifth order can't be Associated or Pan Magic.

Subject equations can be incorporated in a routine to generate Two Way V type ZigZag Magic Squares (ref. ZigZag5).

Attachment 17.02 shows for miscellaneous Magic Sums the first occurring Two Way V type ZigZag Magic Square.

Each square shown corresponds with numerous squares for the applicable Magic Sum and variable values {ai}.

Each square shown corresponds with numerous squares for the applicable Magic Sum and variable values {ai}.

        Four Way V type ZigZag

The defining equations for a Four Way V type ZigZag Pan Magic Square of order 6 can be written as:

a(19) =   - s1 / 3 + a(28) + a(33) + a(35)
a(20) =   - s1 / 3 + a(29) + a(34) + a(36)
a(21) =     s1 / 6 + a(30) - a(33)
a(22) = 2 * s1 / 3 - a(27) - a(29) - a(34)
a(23) = 2 * s1 / 3 - a(28) - a(30) - a(35)
a(24) =     s1 / 6 + a(27) - a(36)
a(25) =     s1 / 2 - a(27) - a(29)
a(26) =     s1 / 2 - a(28) - a(30)
a(31) =     s1 / 2 - a(33) - a(35)
a(32) =     s1 / 2 - a(34) - a(36)

a(18) = s1 / 3 - a(33)
a(17) = s1 / 3 - a(32)
a(16) = s1 / 3 - a(31)
a(15) = s1 / 3 - a(36)
a(14) = s1 / 3 - a(35)
a(13) = s1 / 3 - a(34)

a(12) = s1 / 3 - a(27)
a(11) = s1 / 3 - a(26)
a(10) = s1 / 3 - a(25)
a( 9) = s1 / 3 - a(30)
a( 8) = s1 / 3 - a(29)
a( 7) = s1 / 3 - a(28)

a(6) = s1 / 3 - a(21)
a(5) = s1 / 3 - a(20)
a(4) = s1 / 3 - a(19)
a(3) = s1 / 3 - a(24)
a(2) = s1 / 3 - a(23)
a(1) = s1 / 3 - a(22)

which illustrate the consequential symmetry (complete).

Subject equations can be incorporated in a routine to generate Four Way V type ZigZag Pan Magic Squares (ref. ZigZag6).

Attachment 17.03 shows for miscellaneous Magic Sums the first occurring Four Way V type ZigZag Pan Magic Square.

Each square shown corresponds with numerous squares for the applicable Magic Sum and variable values {ai}.
