Starting structural reductions in SI_LTL mode, iteration 0 : 90/90 places, 121/121 transitions.
Graph (complete) has 53 edges and 90 vertex of which 32 are kept as prefixes of interest. Removing 58 places using SCC suffix rule.1 ms
Discarding 58 places :
Also discarding 64 output transitions
Drop transitions removed 64 transitions
Reduce places removed 1 places and 1 transitions.
Discarding 10 places :
Symmetric choice reduction at 0 with 10 rule applications. Total rules 11 place count 21 transition count 28
