%N For k >= a(n), there are A048284(n) numbers expressible as a sum of exactly k-n k-gonal numbers.

%e For k >= 6, the 2 numbers 2k-1 and 5k-4 are the sum of at best k k-gonal numbers. Hence a(0) = 6.

%e For k >= 9, the 4 numbers k-1, 2k-2, 4k-4 and 5k-5 are the sum of at best k-1 k-gonal numbers. Hence a(1) = 9.

%e For k >= 10, the 6 numbers k-2, 2k-3, 3k-4, 4k-5, 5k-6 and 8k-9 are the sum of at best k-2 k-gonal numbers. Hence a(2) = 10.
