WHEEL METHOD A-1:VARIANT 5 for a 9x9 Square

Picture of a wheel


A Discussion of Variant 5


For this one 9x9 example (out of a total of 192 combinations), variant 5 is set up so that the group of numbers in the left diagonal ½ (n2-n+2) to ½(n2+n) are set up according to the following order 44 → 37 → 39 → 40 → 41 → 42 → 43 → 45 → 38, as shown in the partial complementary template starting at 1:

Using this template (normal) the other diagonal, column and row of the wheel are filled in followed by filling in of the "non-spoke" numbers using 81, 82 or 83 as the only sum pairs as shown in the parity table. Note that using the second entry of this table would make E+E+E disappear from row/column 2 or 8. Using the second entry of 7 would leave row 4 with at least one unallowed 80.

  1. The wheel is first filled in (Squares I-IV).
  2. Fill in row/columns 4 and 6 (all O) (Square V).
  3. Fill in row/columns 2 and 8 (all E) (Square VI).

  4. Fill in the last row/columns 1, 3 and 7, 9 (O+E+E or E+O+O) noting that the rows and columns add up to the requisite pairs.
  5. The last square(VIII) shows the arrangement of the first numbers of each of the two pairs used. (in yellow). These numbers are also clustered symmetrically about the center cell.
  6. An alternative simpler route to this type of square can be used instead. This uses a a color coded method from start to generate a 9x9 square with different arrangements of non-spoke numbers.
