Table of n, a(n) for n=1..55.

The IBM Ponder This July 2013 challenge asks for A(8,3).

EXAMPLE

Three tetrahedra labeled (1, 2, 8, 12) yield the 20 possible sums 3, 4, 5, 6, 10, 11, 12, 14, 15, 16, 17, 18, 21, 22, 24, 25, 26, 28, 32, 36. No more sums can be obtained by different labelings, and no labeling with labels < 12 yields 20 possible sums. Therefore A(4,3) = 12.

Square array A(n,k) begins:

1, 1,  1,  1,  1, 1, 1, 1, ...

1, 2,  2,  2,  2, 2, 2, ...

1, 3,  4,  5,  6, 7, ...

1, 4,  7, 12, 16, ...

1, 5, 12, 24, ...

1, 6, 18, ...

1, 7, ...
