N2 - The average transmission coefficient between two terminals in the quantum percolation model was studied using low-concentration series. In dimensions d ≥ 3 we identify Anderson delocalization transitions, at thresholds consistent with (and more accurate than) previous studies. In d = 2 our new series behave much better than earlier ones, and we find clear evidence for a transition at a finite concentration. Several scenarios for the new transition, and for the nature of the states above it, are discussed.
