摘要：

Space-times admitting a three-parameter group of motions acting on two-dimensional null orbits are considered. A coordinate transformation relating the canonical form of the metrics as given by Petrov (1969) and the apparently more general form given by Defrise (1969) is exhibited. For pure radiation fields the space-time is a PP wave. The general vacuum solution with a cosmological constant is found in closed form.
