The ordering phase transitions in solid methane and the cerium monochalcogenides compared. A test of universality

Using data from literature, it is shown that the antiferrorotational transition in solid methane and antiferromagnetic transition in the Ce monochalcogenides are described by the same n = 4 Ginsburg-Landau-Wilson Hamiltonian. Arguments are given that this agreement still applies in the case of a compressible lattice. The conflicting experimental observations in the two systems seem to violate the universality hypothesis.
