Moore-Mealy Equivalence
IFF A23 = Action(S2,E3), A24 = Action(S2,E4) and A25 = Action(S2,E5) are equivalent, they may all be merged into one common S2 Exit-Action, done just before leaving Prior-State S2.
IFF A12 = Action(S1,E2), A24 = Action(S2,E4) and A36 = Action(S3,E6) are equivalent, they may all be merged into one common S5 Entry-Action, done just after entering Next-State S5.
Otherwise, one extra state may be inserted to split each transition, with a single entry and exit, after which the above conditions are not required.
