From: Nigel BostonResent-Date: Thu, 27 Jul 95 21:44:05 BST Does there exist a 3-generated finite group generated by a cyclic group of order 2 and a non-abelian group of order 21 ? This is a specific case of a question of Ribes and Wong, asked if, given finite groups H and K, there exists a finite group G generated by groups isomorphic to H and K such that d(G) = d(H) + d(K).
