Abstract

Suggested by Scullard's recent star-triangle relation for bond correlated\nsystems, we propose a general "cell/dual-cell" transformation, which allows in\nprinciple an infinite variety of lattices with exact percolation thresholds to\nbe generated. We directly verify Scullard's new site percolation thresholds,\nand derive the bond thresholds for his "martini" lattice (pc = 1/sqrt(2)) and\nthe "A" lattice (pc = 0.625457..., solution to p5 - 4 p4 + 3 p3 + 2 p2 - 1\n= 0). We also present a precise Monte-Carlo test the site threshold for the "A"\nlattice.\n
