Query: Lepton mixing patterns from $PSL_2(7)$ with a generalised CP symmetry   Lepton mixing patterns from the modular group $PSL_2(7)$ with generalised CP
symmetries are studied. The residual symmetries in both charged leptons and
neutrinos sector are $Z_{2}\times CP$. Seven types of mixing patterns at the
$3\sigma$ level of the new global fit data are obtained. Among these patterns,
three types of patterns can give the Dirac CP phase which is in the $1\sigma$
range of the global fit data. The effective mass of neutrinoless double-beta
decay for these patterns are also examined.
