Abstract.   In Theorem 3 we improve a lemma of Thompson omitting one of its conditions. In that lemma the structure of T, a Sylow 2-subgroup of G, is described only. In contrast to that lemma, we describe in detail the structure of the whole group G and embedding of T in G. In Theorem 4 we consider a similar, but more general, situation for groups of odd order.
