The strong approximation theorem and computing with linear groups
We obtain a computational realization of the strong approximation theorem. That is, we develop algorithms to compute all congruence quotients modulo rational primes of a finitely generated Zariski dense group H ≤SL(n, ℤ) for n ≥ 2. More generally, we are able to compute all congruence quotients of a finitely generated Zariski dense subgroup of SL(n, ℚ) for n > 2.
