We theoretically investigate the nature of the state at quarter filled lowest Landau level and predict that, as the quantum well width is increased, a transition occurs from the composite fermion Fermi sea into a novel non-Abelian fractional quantum Hall state that is topologically equivalent to -wave pairing of composite fermions. This state is topologically distinct from the familiar -wave paired Pfaffian state. We compare our calculated phase diagram with experiments and make predictions for many observable quantities.
