Abstract

A finite group

G

is called \textit{

(l, m, n)

-generated}, if it is a quotient group of the triangle group

T (l, m, n) = ⟨ x, y, z | x^{l} = y^{m} = z^{n} = x y z = 1 ⟩ .

In 29, Moori posed the question of finding all the

(p, q, r)

triples, where

p, q

and

r

are prime numbers, such that a non-abelian finite simple group

G

is a

(p, q, r)

-generated. In this paper we establish all the

(p, q, r)

-generations of the symplectic group

S p (6, 2) .

GAP 20 and the Atlas of finite group representations 33 are used in our computations.
