A presentation for the subgroup of compressed conjugating automorphisms of a partially commutative group

‎Let GΓ be a partially commutative group. We find a finite presentation for the subgroupConjV(GΓ) of compressed vertex conjugating automorphisms of the automorphism group Aut(GΓ) of G. We have written GAP packages which compute presentations for Aut(GΓ) and its subgroups Conj(GΓ) and ConjV(GΓ).
