Abstract: We study the lattice reaction diffusion model 3A -> 4A, A -> 0 ``tripletcreation- using numerical simulations and n-site approximations. Thesimulation results provide evidence of a discontinuous phase transition at highdiffusion rates. In this regime the order parameter appears to be adiscontinuous function of the creation rate; no evidence of a stable interfacebetween active and absorbing phases is found. Based on an effective mapping toa modified compact directed percolation process, shall nevertheless argue thatthe transition is continuous, despite the seemingly discontinuous phasetransition suggested by studies of finite systems.
