Abstract
We numerically investigate the spectral statistics of quasienergies fo r the unitary network operator U of the Chalker-Coddington network. Th e shape of the level spacing distribution as well the scaling of its m oments is compared to known results for quantum Hall systems. We also discuss the influence of multifractality on the tail of the spacing di stribution.
