Abstract

We provide a simple presentation by generators and relations of the ring of $\omega$-invariant symmetric polynomials over the field $\mathbb{F}_{2}$. Here, $\omega$ denotes the standard involution on the ring of symmetric polynomials, interchanging the elementary symmetric polynomials with the complete homogeneous symmetric polynomials. Along the way, we prove several important properties of this involution in the specific setting of characteristic 2.
