EXAMPLE
Array begins:
1;
1, 2;
1, 1, 3;
1, 3, 3, 4;
1, 2, 6, 4, 5;
1, 4, 7, 6, 5, 6;
1, 3, 10, 11, 10, 6, 7;
1, 5, 11, 16, 14, 12, 7, 8;
1, 4, 15, 20, 22, 14, 14, 8, 9;
1, 6, 16, 26, 28, 29, 20, 16, 9, 10;
...
T(6,3) = 7 because the partitions of 6 into 3 parts are 4+1+1, 3+2+1, 2+2+2,
the multiplicities are (1,2), (1,1,1), (3),
the distinct multiplicities are respectively (1,2), (1), (3),
contributing 3+1+3 = 7.
