  We continue research into the cyclically presented groups with length three
positive relators. We study small cancellation conditions and SQ-universality,
we obtain the Betti numbers of the groups' abelianisations, we calculate the
orders of the abelianisations of some groups, and we study isomorphism classes
of the groups. Through computational experiments we assess how effective the
abelianisation is as an invariant for distinguishing non-isomorphic groups.
