NAME

Square array, read by antidiagonals, where the n-th row is the n-th binomial transform of the natural numbers, with T(0,k) = (k+1) for k>=0.

COMMENTS

The main diagonal is A089945: {T(n,n)=(2*n+1)*(n+1)^(n-1), n>=0}; the hyperbinomial transform of the main diagonal is the next lower diagonal in the array (A089946): {T(n+1,n) = 2*(n+1)*(n+2)^(n-1), n>=0}.

FORMULA

T(n, k) = (k+n+1)*(n+1)^(k-1). E.g.f.: (1+x)*exp(x)/((1-y*exp(x)).

E.g.f.: (1+x)*exp(x)/((1-y*exp(x)).

COMMENTS

The main diagonal is A089945: {T(n,n)=(2*n+1)*(n+1)^(n-1), n>=0}; the hyperbinomial transform of the main diagonal is the next lower diagonal in the array (A089946): {T(n+1,n)=2*(n+1)*(n+2)^(n-1), n>=0}.

FORMULA

T(n,k)=(k+n+1)*(n+1)^(k-1). E.g.f.: (1+x)*exp(x)/((1-y*exp(x)).
