Results are presented of Monte Carlo simulations for a three-dimensional nearest-neighbour Ising spin glass model with a '+/-J' distribution of interactions on a simple cubic lattice. The data for the spin glass susceptibility, the correlation length and the logarithm of an 'average' relaxation time are consistent with a transition at T=0. However, a similarly good fit is also obtained with a finite transition temperature, Tc, if Tc<or approximately=1 (in units of J). In addition, earlier data on the corresponding two-dimensional model are re-analysed.
