An algorithm for the computation of the plethysm
of two symmetric functions

Let h_n the homogenous symmetric function of degree n. You can look at
it as the generating function of weakly increasing sequences of integers
of length n. Let m_I the monomial symmetric function. You can look at
it as the generating function of weakly increasing sequeces, whose weight
is a permutation of I.
We will give an algorithm to compute the decomposition of the plethysm
S_n[m_I] as a sum of monomial symmetric functions.
