COMMENT
|
This becomes triangle A009998(n-1,m-1), n>=m>=1, if the m-th column entries are divided by m^(m-1).
Row sums give A076015. The m-th column (without leading zeros) gives (m^(m-1))powers of m, m>=1.
a(n,m)=sum(stirling2(n,p)A008279(m-1,p-1),p=1..m), n>=m>=1, else 0.

|
FORMULA
|
a(n, m)=m^(n-1), n>=m>=1, else 0.
G.f. for m-th column: (m^(m-1))(x^m)/(1-m*x), m>=1.
