On groups saturated with dihedral groups and linear groups of degree 2
The paper establishes the structure of periodic groups and Shunkov groups saturated with groups consisting of the groups M consisting of the groups L<sub>2</sub>(q), where q = 3, 5 (mod 8) and dihedral groups with Sylow 2-subgroup of order 2. It is proved that a periodic group saturated with groups from M is either isomorphic to a prime Group L<sub>2</sub> (Q) for some locally-finite field Q, or is isomorphic to a locally dihedral group with Sylow 2-subgroup of order 2. Also, the existence of the periodic part of the Shunkov group saturated with groups from the set M is proved, and the structure of this periodic part is established.
