We study numerical invariants d\TC(Γ) and d\cat(Γ) of groups recently introduced in \citeDJ and independently in \citeKW. We compute d\TC for finite cyclic groups \mathbb Zp with prime p as well as for nonorientable surfaces of genus g>3 (for orientable surfaces it was computed in \citeDJ). We prove the formula d\TC(G∗ H)=max\d\TC (G),d\TC (H), \cd(G× H)\ for torsion free groups.
