In this review article we discuss four recent methods for computing
Maurer-Cartan structure equations of symmetry groups of differential equations.
Examples include solution of the contact equivalence problem for linear
hyperbolic equations and finding a contact transformation between the
generalized Hunter-Saxton equation and the Euler-Poisson equation.
