A group G is said to be (l,m,n)-generated if it is a quotient of the triangle group T(l,m,n) =<x,y,z | xl =ym =zn =xyz =1>.Moori posed in 1993 the question of finding all the triples (l,m,n) such that non-abelian finite simple groups are (l,m,n)-generated.We partially answer this question for the Fischer sporadic simple group Fi23.In particular,we investigate all (2,q,r)-generations for the Fischer sporadic simple group Fi23,where q and r are distinct prime divisors of |Fi23|.
