摘要：

We compute the cohomology of the principal congruence subgroup Gamma(2)(4) subset of Sp(4)(Z) consisting of matrices gamma = 1 mod 4. This is done by computing the cohomology of the moduli space M-4. We determine the mixed Hedge structure on this cohomology, as well as the intersection cohomology of the Satake compactification of M-4.
