In this paper we determine the classical simple groups of dimension r=3,5
which are (2,3)-generated (the cases r = 2, 4 are known). If r = 3, they are
PSL_3(q), q 4, and PSU_3(q^2), q^2 9, 25. If r = 5 they are PSL_5(q), for
all q, and PSU_5(q^2), q^2 >= 9. Also, the soluble group PSU_3(4) is not
(2,3)-generated. We give explicit (2,3)-generators of the linear preimages, in
the special linear groups, of the (2,3)-generated simple groups.Comment: 12 page
