 OFFSET 1,2 COMMENTS Numbers occurring at least three times in the triangle A309992. All terms are contained in A325593 and in A325901. LINKS Alois P. Heinz, Table of n, a(n) for n = 1..318 Wikipedia, Multinomial coefficients Wikipedia, Partition (number theory) EXAMPLE 1 is in the sequence because M(0;0) = M(1;1) = M(2;2) = M(3;3) = ... = 1. 105 is in the sequence because M(7;4,2,1) = M(15;13,2) = M(105;104,1) = 105. 120 is in the sequence because M(10;7,3) = M(16;14,2) = M(120;119,1) = 120. 1365 is in the sequence because M(15;11,4) = M(15;12,2,1) = M(1365;1364,1) = 1365.
