COMMENTS
| Row sums are:
{1, 3, 13, 75, 541, 4683, 47293, 545835, 7087261, 102247563}.
This sequence has logical conjugate substitution :
2x->1-2x;
of the function:
q(x,n)=If[n == 0, 1, (2*x)^(n + 1)*PolyLog[ -n, 1 - 2*x]].

FORMULA
| p(x,n)=(1 - 2*x)^(n + 1)*PolyLog[ -n, 2*x]/(2*x); t(n,m)=corefficients(p(x,n)).
