%N A013588 Smallest positive integer not the determinant of an n X n 0-1 matrix.
%C A013588 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.
