Abstract

Throughout this book by a group G we an mean abelian (i.e., commutative) group using for the binary operation the additive notation. The order of a group G is the cardinal number |G| of the set of its elements. If |G| is a finite (countable) cardinal number then G is called a unite (countable) group.
