Nature of problem:
The classical problem of constructing formal integrals for a Hamiltonian of harmonic oscillators coupled by polynomial interactions is considered.

Solution method:
An algorithm recently proposed is applied which allows very fast computation of the integrals.

The restrictions, imposed by array dimensions, are described in tdetail in the long write up.

Running time:
The computation of one integral up to order 8 for a model with 2 degrees of freedom required an execution time of about 25 s on the UNIVAC 1106.
