Query: Soft $A_4 \to Z_3$ Symmetry Breaking and Cobimaximal Neutrino Mixing   I propose a model of radiative charged-lepton and neutrino masses with $A_4$
symmetry. The soft breaking of $A_4$ to $Z_3$ lepton triality is accomplished
by dimension-three terms. The breaking of $Z_3$ by dimension-two terms allow
cobimaximal neutrino mixing $(\theta_{13} \neq 0, \theta_{23} = \pi/4,
\delta_{CP} = \pm \pi/2)$ to be realized with only very small finite calculable
deviations from the residual lepton triality. This construction solves a
long-standing technical problem inherent in renormalizable $A_4$ models since
their inception.
