© 2018 World Scientific Publishing Company The automorphism group of a partially commutative group (Formula presented.) is generated by four types of automorphism: graph automorphisms, inversions, transvections and vertex conjugating automorphisms. We find a characterisation of the subgroup (Formula presented.) generated by inversions and transvections, in terms of stabilisers of subgroups of (Formula presented.) generated by the so-called “admissible” subsets of (Formula presented.). This is used to give a decomposition of (Formula presented.) as a chain of semi-direct products of (mostly) tractable and recognisable subgroups; which in turn gives rise to a presentation of (Formula presented.).
