We investigate envelope solitons of circularly polarized electromagnetic waves in a cold plasma, due to the joint action of relativistic and striction nonlinearities. It is shown that in the approximation in which the plasma perturbations are quasineutral there exist only soliton small-amplitude solutions in which the oscillatory velocity of the electron is much lower than the velocity of light. Numerical integration with a computer yielded solitons with relativistic amplitudes, for which the plasma charge separation is substantial. These solitons differ in shape from ordinary small-amplitude solitons and have a discrete velocity spectrum. It is demonstrated that the concentration has a limit above which the plasma has no solitons with a specified carrier frequency.
