Abstract: It is proved that the hypercentral residual of a group of finite rank, generated by two subnormal subgroups, is the join of the hypercentral residuals of the generating subnormal subgroups. The theorem is subject to the condition that, when factored by their hypercentral residuals, these groups are hypercentral.
