Some computations always involve rational representations/bases, for example when decomposing permutation representations of (various products of) symmetric groups.
We can first use an adhoc Matlab implementation that delegates to double-encoded integers or java.math.BigInteger. See the replab.Rational class in this branch https://github.com/replab/replab/pull/356.
