Abstract

The problem of counting the different ways of folding the planar triangular lattice is shown to be equivalent to that of counting the possible 3-colourings of its bonds, a dual version of the 3-colouring problem of the hexagonal lattice solved by Baxter. The folding entropy log q per triangle is thus given by Baxter’s formula $\sqrt{3}\Gamma (1/3)$$^{3/2}$ /2$\pi$ = 1.2087
