From free idempotent monoids to free multiplicatively idempotent rigs
A multiplicatively idempotent rig (which we abbreviate to mirig) is a rig
satisfying the equation r2 = r. We show that a free mirig on finitely many
generators is finite and compute its size. This work was originally motivated
by a collaborative effort on the decentralized social network Mastodon to
compute the size of the free mirig on two generators.
