Abstract: Studying the mirror symmetry of a Calabi-Yau threefold $ X$ of the Reye congruence in $ \mathbb{P}^4$, we conjecture that $ X$ has a non-trivial Fourier-Mukai partner $ Y$. We construct $ Y$ as the double cover of a determinantal quintic in $ \mathbb{P}^4$ branched over a curve. We also calculate BPS numbers of both $ X$ and $ Y$ (and also a related Calabi-Yau complete intersection $ \tilde X_0$) using mirror symmetry.
