The category of supercommutative algebras.

An \(R\)-supercommutative algebra is an \(R\)-super algebra \(A = A_0 \oplus A_1\) endowed with an \(R\)-super algebra structure satisfying:

\[x_0 x'_0 = x'_0 x_0, \qquad x_1 x'_1 = -x'_1 x_1, \qquad x_0 x_1 = x_1 x_0,\]

for all \(x_0, x'_0 \in A_0\) and \(x_1, x'_1 \in A_1\).

Return the extra super categories of self.

A signed tensor product of supercommutative algebras is a supercommutative algebra.
