摘要：

The universal covering symmetry algebra of the Robinson-Trautman equations of Petrov Type III is shown to include the infinite-dimensional Lie algebra A(2) circle plus C[lambda(-1), lambda], the loop algebra over A(2). This algebra has slower growth than the contragradient algebra K-2 obtained previously for this metric by other authors.
