(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A013588 Smallest positive integer not the determinant of an n X n 0-1 matrix. 6
2, 2, 3, 4, 6, 10, 19, 41, 103, 269 (list; graph; refs; listen; history; text; internal format)



This majorizes the sequence of maximal determinants only up to the 6th term. It is conjectured that the sequence of maximal determinants majorizes this for all later terms. The 8th term has not been independently verified.

There is no 3 X 3 0-1 matrix with determinant 3, as such a matrix must have a row with at least one 0 in it.
