The number of sufficient and necessary conditions for CP conservation with Majorana neutrinos: Three or four?

As is well-known, there exist totally three CP-violating phases in the leptonic sector if three ordinary neutrinos are massive Majorana particles. In this short note, we raise the question whether the number of sufficient and necessary conditions for CP conservation in the leptonic sector with massi...
