MAGIC SQUARES 149

A very different construction for a square of the same size,
or order, as the one above is by means of two preliminary
squares. In square A, the numbers 1 to 5 inclusive are placed
in the top row in any ofder preferred. The second row begins
with the number in the fourth sub-square of the first row and
this is followed by the remaining numbers in the same rela-
tive order. Each successive row commences with the number
in the fourth sub-square of the previous row.

 

Square A

Square B is built up from the numbers o, 5, 10, 15 and 20.
These numbers are placed in the top row in any order. Each
successive row starts with the number in the third sub-square
of the previous row, and the other numbers then follow in the
same relative order.
