A recent paper studied an inverse submonoid $M_n$ of the rook monoid, byrepresenting the nonzero elements of $M_n$ via certain triplets belonging to$\mathbb{Z}^3$. In this short note, we allow the triplets to belong to$\mathbb{R}^3$. We thus study a new inverse monoid $\overline{M}_n$, which is asupermonoid of $M_n$. We point out similarities and find essential differences.We show that $\overline{M}_n$ is a noncommutative, periodic, combinatorial,fundamental, completely semisimple, and strongly $E^*$-unitary inverse monoid.

An extension to "A subsemigroup of the rook monoid"
