Аннотация

In the present paper there are derived and described some groups of − symmetry with initial cyclical group of permutation by second order, who have in quality of generating groups the cristallografic punctual groups of classical symmetry. Keywords: generalized symmetries, groups, right quasi-homeomorphisms, wreath product of two groups.
