### Maass cusp forms for GSp(4)

Currently in the LMFDB, we have data on L-functions associated to Maass cusp forms for GSp(4) of level 1. These satisfy a functional equation with $\Gamma$-factors $$\Gamma_\R(s + i \mu_1)\Gamma_\R(s + i \mu_2)\Gamma_\R(s - i \mu_1)\Gamma_\R(s - i \mu_2)$$ with $0 \le \mu_2 \le \mu_1$.

#### Maass cusp forms of level 1

The dots in the plot correspond to L-functions with $(\mu_1,\mu_2)$ in the $\Gamma$-factors, colored according to the sign of the functional equation (blue indicates $\epsilon=1$). These have been found by a computer search. Click on any of the dots to get detailed information about the L-function.
