Abstract: Earlier D. G. Higman classified the finite groups of order *n*, such that *n* is divisible by 3 to the first power, with the assumption that the centralizer of *X*, where *X* is a subgroup of order 3, is a cyclic trivial intersection set of even order 3*s*. In this paper the theorem is generalized to include all prime numbers greater than 3. With an additional assumption: , we have proved that one of the following holds for these groups, hereafter designated as *G*:

(A) *G* is isomorphic to , where ;

(B) there exists a normal subgroup of odd index in *G*, and a normal subgroup *N* of of index 2 such that where .
