الملخص EN

This paper obtains the exact solutions of the ϕ4 equation.

The Lie symmetry approach along with the simplest equation method and the Exp-function method are used to obtain these solutions.

As a simplest equation we have used the equation of Riccati in the simplest equation method.

Exact solutions obtained are travelling wave solutions.
