Alois P. Heinz, Rows n = 1..200, flattened
FORMULA
If n>k>0 T(n, k)=sum_j[S(n-k, j)] over k>j and if n>0 T(n, n)=1; where S(n, k)=A059882(n, k) and if n>k>0, S(n, k)=sum_j[T(n-k, j)] over j>k (note reversal) and if n>0 S(n, n)=1.
EXAMPLE
Rows start (1,0,0,0,0,...), (1,1,0,1,...), (1,1,1,...) etc. T(10,4)=6 since 10 can be written as 4+2+4, 4+2+3+1, 4+1+5, 4+1+4+1, 4+1+3+2, or 4+1+2+1+2.
