A symmetric Airy electron plasma (SAiEP) wave, which is caused by launching four Airy beams symmetrically in the initial plane in an unmagnetized collisionless plasma, is analytically investigated in this paper. In addition to intensity distributions, evolutions, and the potential of the SAiEP wave with different parameters, the difference between the SAiEP wave and the Airy-like electron plasma wave is studied as well. The results show that the SAiEP wave with different distances between the main lobes in the initial plane behaves differently as the decay factor changes. When the decay factor increases, the frequency and the amplitude of the potential become smaller. Besides, the SAiEP wave has the autofocusing property, while the Airy-like electron plasma wave has the weak diffraction property.
