%N Positive determinant values assumed by performing all permutations of entries in the 3 X 3 matrix of A301372.
%C A 3 X 3 matrix with given 9 matrix entries can produce A088021(3)=10080 distinct determinants if all positional permutations are performed. The current sequence provides the 5040 positive determinants of a conjectured optimal matrix minimizing its greatest matrix entry.

%e a(1) = 27 because the smallest determinant that can be achieved from the matrix entries of A301372 is
%e det (( 0 1 89)
%e (87 99 97)
%e (54 61 20)) = 27,
%e .
%e a(5040) = 1039208:
%e det ((99 54 1)
%e (20 97 87)
%e (61 0 89)) = 1039208.
