Also discarding 5 output transitions
Drop transitions (Output transitions of discarded places.) removed 5 transitions
Drop transitions (Empty/Sink Transition effects.) removed 2 transitions
Reduce isomorphic transitions removed 2 transitions.
Drop transitions (Trivial Post-Agglo cleanup.) removed 5 transitions
Trivial Post-agglo rules discarded 5 transitions
Performed 5 trivial Post agglomeration. Transition count delta: 5
