  Recently, Prasad and Yeung classified all possible fundamental groups of fake
projective planes. According to their result, many fake projective planes admit
a nontrivial group of automorphisms, and in that case it is isomorphic to
$\bbZ/3\bbZ$, $\bbZ/7\bbZ$, $7:3$, or $(\bbZ/3\bbZ)^2$, where $7:3$ is the
unique non-abelian group of order 21.
  Let $G$ be a group of automorphisms of a fake projective plane $X$. In this
paper we classify all possible structures of the quotient surface $X/G$ and its
minimal resolution.
