Let $G_{\Gamma}$ be a partially commutative group. We find a finite presentation for the subgroup $Conj_v(G_{\Gamma})$ of compressed vertex conjugating automorphisms of the automorphism group $Aut(G_{\Gamma})$ of $G$. We have written GAP packages which compute presentations for $Aut(G_{\Gamma})$ and its subgroups $Conj(G_{\Gamma})$ and $Conj_v(G_{\Gamma})$.
