Query: On Calabi-Yau threefolds with large nonabelian fundamental groups   In this short note we construct Calabi-Yau threefolds with nonabelian
fundamental groups of order 64 as quotients of the small resolutions of certain
complete intersections of quadrics in $\PP^7$ that were first considered by M.
Gross and S. Popescu.
