Calabi-Yau quotients with terminal singularities

In this paper we are interested in quotients of Calabi-Yau threefolds with isolated singularities. In particular, we analyze the case when $X\mathrm{/}G$ has terminal singularities. We prove that, if $G$ is cyclic of prime order and $X\mathrm{/}G$ has terminal singularities, then $G$ has order $2,3$ or $5$.
