This paper deals with problems connecting with decomposition of groups into double cosets. It is established a relation between double decomposition and usual decomposition by subgroups for groups which can be decompose into a generalized free products and groups with free complementarity of subgroups.
Mots-clés : group, double decomposition index
Keywords: algorithmic problem, subgroup, subgroup index, double coset, free product, free complementarity of subgroups.
