Mutations of $\mathfrak{perm}$ algebras

Abstract: We describe mutation elements in free $\mathfrak{perm}$ algebras. Moreover, we construct a base of free mutation of free $\mathfrak{perm}$ algebra. Using Cohn's criterion for the specialty of algebras, we show that there is an exceptional homomorphic image of mutation of free $\mathfrak{perm}$ algebras.
