Complete homogeneous symmetric functions

Complete homogeneous symmetric functions are defined in power sum basis via generating function

(1)

For these polynomials are given as

Sym = SymmetricFunctions(QQ)
h = Sym.h()
p = Sym.p()
arr = [[i, p(h[i])]
       for i in  range(1,5)];
table(arr, frame=True)

They, as all symmetric functions, possess generalization
