Let m[lambda] be the monomial symmetric function in
negative shifts of the discrete variables, corresponding
to the partition lambda
The recurrence satisfied by the MacMahon Master Theorem product
with , 2, variables , is
a[2, 2] a[1, 1] - a[2, 1] a[1, 2] - a[2, 2] M[1] - M[2] a[1, 1] + M[2] M[1]
This took , 0.138, seconds
