Please make a donation to keep the OEIS running. We are now in our 56th year. In the past year we added 10000 new sequences and reached almost 9000 citations (which often say "discovered thanks to the OEIS").

A322576 Least nonnegative integer that can not be expressed as the determinant of an n X n matrix whose entries are a permutation of the multiset {1^n,..,n^n}. 4

Table of n, a(n) for n=1..8.

EXAMPLE

a(1) = 0 because det[1] = 1.

a(2) = 1 because det[1,1; 2,2] = 0 and det[2,1; 1,2] = 3 are the only determinant values >= 0 that can be made by permuting the matrix entries {1,1, 2,2}.

a(3) = 9, because it the first missing value in the list of A309799(3) = 13 determinant values corresponding to {1,1,1, 2,2,2, 3,3,3}: 0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 13, 15, 18.
