In this work we study percolation on a graph for which the number of in nite open clusters presents three non-trivial phases, corresponding to the existence of zero, in nite or a unique cluster. This graph, called L, is the direct product of a regular tree T and the line Z, in which each \tree" edge is open with probability and each \line" edge with probability Y. All work developed here is a speci c analysis of the article Percolation in 1+1 Dimensions, by Grimmett e Newman, whose the main purpose is de ne the behavior of the curves that divide the three regions, representative of three phases in the unit square, from the possible values of the ordered pair ((t,y).
