Non-orientable minimal limit volume conjecture

Let $V_8$ denote the volume of the regular ideal octahedron, and consider non-orientable hyperbolic $3$-manifolds with increasingly many cusps.

Non-orientable minimal limit volume conjecture. The minimal limit volume of non-orientable hyperbolic $3$-manifolds is $V_8$.

The source presents this as a further possible result following the orientable asymptotic volume conjecture. It supplies no precise definition of “minimal limit volume” or proof, so the formulation and status require verification.
