## Abstract

We classify and discuss the possible nonorthogonal coordinate systems which lead to R-separable solutions of the wave equation. Each system is associated with a pair of commuting operators in the symmetry algebra so (3,2) of this equation, one operator first order and the other first or second order. Several systems appear here for the first time.
