      On groups with biprimary subgroups of even order 

      Sokhor, Irina Leonidovna; Monakhov, Victor Stepanovich; Сохор, Ирина Леонидовна (2017)
      We investigate groups in which maximal subgroups 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 applications ...
