Support contains 174 out of 4030 places. Attempting structural reductions.
Starting structural reductions in REACHABILITY mode, iteration 0 : 4030/4030 places, 4020/4020 transitions.
Discarding 2 places :
Also discarding 1 output transitions
Drop transitions (Output transitions of discarded places.) removed 1 transitions
Remove reverse transitions (loop back) rule discarded transition t4018 and 2 places that fell out of Prefix Of Interest.
Drop transitions (Empty/Sink Transition effects.) removed 1 transitions
Reduce isomorphic transitions removed 1 transitions.
Drop transitions (Trivial Post-Agglo cleanup.) removed 1922 transitions
Trivial Post-agglo rules discarded 1922 transitions
Performed 1922 trivial Post agglomeration. Transition count delta: 1922
