Abstract

We consider the cyclically presented groups defined by cyclic presentations with 2m2m generators xix_i whose relators are the 2m2m positive length three relators xixi+1xi+m1x_ix_{i+1}x_{i+m-1}. We show that they are hyperbolic if and only if m{1,2,3,6,9}m\in \{1,2,3,6,9\}. This completes the classification of the hyperbolic cyclically presented groups with positive length three relators.
