WebJun 15, 2024 · In Section 5 we exhibit explicit algorithms to decide whether G = 〈 A, B 〉 ≤ SL 2 (R) is discrete. The group G is called elementary if the commutators [ g , h ] = g h g − 1 h − 1 of all pairs g , h ∈ G of infinite order have trace 2. WebGROWTH AND GENERATION IN SL2(Z/pZ) 603 If A equals the projection of a fixed set of generators of a free group in SL/2(Z) (take, e.g., A as in (1.2) or (1.3)) it follows by a simple argument that A must grow rapidly at first when multiplied by itself. In such a situation, we obtain a bound of diam(r(SL2(Z/pZ), A)) < logp,
