The enhanced binary tree (EBT) is a nontransitive graph which has two percolation thresholds pc1 and pc2 with pc1 < pc2. Our Monte Carlo study implies that the second threshold pc2 is significantly lower than a recent claim by Nogawa and Hasegawa (2009 J. Phys. A: Math. Theor. 42 145001). This means that pc2 for the EBT does not obey the duality relation for the thresholds of dual graphs which is a property of a transitive, nonamenable, planar graph with one end. As in regular hyperbolic…

By applying the substitution method to known bounds of the order-5 pentagonal tiling, it is shown that p(c2) ≥ 0.382508 for theOrder-5 square tiler, p( c2) ≤ 0.472043 for its dual, and p(C2)≥ 0.275768 for the order -5-4 rhombille tiling.

It is found that the crossing probability increases gradually from 0 to 1 as p increases from the lower p_{l} to the upper p_{u} critical values, and bounds and estimates are found for the values of p l and p u for these lattices.
