A088216 Smallest nonnegative number not expressible as determinant of an n X n matrix with elements 1..n^2. 10
0, 324, 38831, 6773999, 1859163031 (list; graph; refs; listen; history; text; internal format)

LINKS

Table of n, a(n) for n=2..6.

Hugo Pfoertner, Find all possible values of det(A) for matrix with elements 1..n^2. FORTRAN program.

EXAMPLE

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.

CROSSREFS

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

Cf. A085000, A088215, A088217, A322576.

Sequence in context: A128992 A221399 A204082 * A121001 A203029 A298101
