We continue the study of the cyclically presented groups G = G(n)(w) where w = x(0)x(i)(-alpha)x(j)(-alpha)x(i)(alpha)x(j)(beta). We prove that under certain conditions on the parameters n, i, j, alpha, beta the group G is infinite. These results support our conjecture which states for n > 4 exactly when G is trivial and that if G is non-trivial then G is infinite. (C) 2011 Elsevier Inc. All rights reserved.
