摘要：
In this work we derive symmetry reductions and exact solutions for an inhomogeneous equation that model fast diffusion. We find the connection between classes of nonclassical symmetries of the equation and of an associated system. These symmetries allow us to increase the number of solutions. Some of theses solutions are unobtainable by classical symmetries.
