In his study of groups of 2-rank 3, Alperin showed that if G is a group having an elementary abelian subgroup E of order 8 with C0 (E) of 2-rank 3 and NO (E)/CO (E)£ L3 (2), then the Sylow 2-subgroup of CO {E) is a homocyclic abelian group, V. Also, he explicitly found the possibilities for the Sylow 2-subgroup P of NO (E). Alperin found P=<(vl9 v2, v3, s,£}, with V=(vv v2, v3y^ Z2n x Z2» x Z2», and vx 8= v2, v2 8= v3, v3 8= vxvz~ rv3i and vx l= V3-1, v2*= v^ 1, vj= t^-1.
