Some properties of abnormal subgroups in generalized soluble groups are considered. In particular, the transitivity of abnormality in metahypercentral groups is proven. Also it is
proven that a subgroup H of a radical ...

Let p, q > 2 be relatively prime integers and
let Hp,q be the generalized Hecke group associated to p and q. The
generalized Hecke group Hp,q is generated by X(z) = −(z − λp)−1
and Y (z) = −(z + λq) −1 where λp = 2 cos ...
We investigate groups in which maximal sub-
groups of even order are primary or biprimary. We also research
soluble groups with restriction on a number of prime devisors of some
proper subgroup orders. We give ...
