Query: Flat manifolds with homogeneous holonomy representation   We show that a rational holonomy representation of any flat manifold except
torus must have at least two non-equivalent irreducible subrepresentations. As
an application we show that if a K\"ahler flat manifold is not a torus then its
holonomy representation is reducible.
