Abstract
We study the mixed and periodic groups with involutions and finite elements which are saturated by finite Frobenius groups. We prove that a group \( G \) of \( 2 \)-rank 1 of even order greater than 2 splits into the direct product of a periodic abelian group \( F \) and the centralizer of an involution; moreover, each maximal periodic subgroup in \( G \) is a Frobenius group with kernel \( F \). We characterize one class with the saturation condition. We prove that a group of \( 2 \)-rank greater than 1 with finite elements of prime orders is a split extension of a periodic group \( F \) by a group \( H \) in which all elements of prime orders generate a locally cyclic group; moreover, every element in \( F \) with every element of prime order in \( H \) generates a finite Frobenius group. Under the condition of the triviality of the local finite radical, we determine some properties of the subgroup \( F \).
