COMMENTS

Named after Matt Parker, who attempted (and failed) to create a 3 X 3 magic square of squares (still an open problem). The sum of entries in the rows, columns and one diagonal is 3051, but in the other diagonal the sum is 4107. Moreover, three entries are repeated (1^2, 29^2 and 41^2).
Cain (2019) cites this trivial semimagic square and calls a finite field a Parker field if no 3 X 3 magic square of squares can be constructed using 9 distinct squared elements.

EXAMPLE

The Parker Square is:
[ 841 1 2209 ]
[ 1681 1369 1 ]
[ 529 1681 841 ]
Or equivalently:
[ 29^2 1^2 47^2 ]
[ 41^2 37^2 1^2 ]
[ 23^2 41^2 29^2 ]
