Comments

Numbers occurring at least three times in the triangle A036038.

Examples

			1 is in the sequence because M(0;0) = M(1;1) = M(2;2) = M(3;3) = ... = 1.
6 is in the sequence because M(6;5,1) = M(4;2,2) = M(3;1,1,1) = 6.
56 is in the sequence because M(56;55,1) = M(8;5,3) = M(8;6,1,1) = 56.
