P[n1](x) * P[n2](x) = sum( H(l) * P[l](x), l, 0,n2), where H() are
n1 must appear somehow. Otherwise:
P[n1](x) = sum( H(l) * P[l](x), l, 0,n2)/ P[n2](x)
for all n1 < n2, and therefore P[i](x) = P[j](x) for all values of i, j.
And this probably leads to a contradiction. There is something missing
You also don't say what you want to do with this identity. Do you want to
simplify expressions involving products of P's? Do you want to determine
P[i] for various i?
