Abstract: We describe an algorithm for computing finitely many terms of a free ZG-resolution of Z for G a finite index subgroup of SL2(Z[1/m]). An implementation of the algorithm is used to determine the integral homology groups Hn(SL2(Z[1/m]); Z) for all integers m = 0. For m = 30 or m = 42 the implementation is practical only for n = 1; 2.
