Support contains 8 out of 434 places. Attempting structural reductions.
Starting structural reductions in LTL mode, iteration 0 : 434/434 places, 7344/7344 transitions.
Discarding 1 places :
Symmetric choice reduction at 0 with 1 rule applications. Total rules 1 place count 433 transition count 7216
Iterating global reduction 0 with 1 rules applied. Total rules applied 2 place count 433 transition count 7216
Applied a total of 2 rules in 36 ms. Remains 433 /434 variables (removed 1) and now considering 7216/7344 (removed 128) transitions.
