%N Smallest nonnegative number not expressible as determinant of an n X n matrix with elements 1..n^2.

%H Hugo Pfoertner, <a href="http://www.randomwalk.de/sequences/a088238.txt">Find all possible values of det(A) for matrix with elements 1..n^2.</a> FORTRAN program.

%e a(2)=0 because the 2 X 2 determinant of a matrix with entries that are permutations of 1,2,3,4 can only assume the values +-2,+-5,+-10.

%Y a(3)=A088214(1), a(4)=A088237(1), a(5)=A088238(1), a(6)=A325900(1).

%Y Cf. A085000, A088215, A088217, A322576.
