Support contains 6 out of 990 places. Attempting structural reductions.
Starting structural reductions in LTL mode, iteration 0 : 990/990 places, 1038/1038 transitions.
Discarding 46 places :
Symmetric choice reduction at 0 with 46 rule applications. Total rules 46 place count 944 transition count 946
Iterating global reduction 0 with 46 rules applied. Total rules applied 92 place count 944 transition count 946
Applied a total of 92 rules in 58 ms. Remains 944 /990 variables (removed 46) and now considering 946/1038 (removed 92) transitions.
