In this paper a new family of quotients of the triangle group[ x , y , z | x 2 = y 3 = z 7 = x y z = 1 ]is obtained. Each group in this family is constructed as central product of the groups SL(2, q ) for various prime‐powers q , and in this way it is shown that for every positive integer s there are infinitely many Hurwitz groups with a centre of size 2 8 .
