Abstract：We study the principally polarized superspecial abelian surfaces over the prime finite field F_p with Frobenius endomorphism π=±sqrt{p}. We give a description of this set in terms of double coset spaces and obtain an explicit formula for its cardinality. This is a joint work with Prof. Chia-Fu Yu.
