SUMMARY
Every group G of order pk, where p is a prime number and k ≥ 1, contains a subgroup of order p. This conclusion is derived from the application of Sylow's theorems, specifically the existence of p-subgroups in finite groups. The discussion highlights the importance of analyzing the order of elements within G to establish the existence of such subgroups. Participants in the forum provided guidance on proving subgroup conditions and emphasized the relevance of group order in this context.
