Support contains 1 out of 1520 places. Attempting structural reductions.
Starting structural reductions in LTL mode, iteration 0 : 1520/1520 places, 1946/1946 transitions.
Discarding 9 places :
Symmetric choice reduction at 0 with 9 rule applications. Total rules 9 place count 1511 transition count 1937
Iterating global reduction 0 with 9 rules applied. Total rules applied 18 place count 1511 transition count 1937
Ensure Unique test removed 1 transitions
Reduce isomorphic transitions removed 1 transitions.
Iterating post reduction 0 with 1 rules applied. Total rules applied 19 place count 1511 transition count 1936
Discarding 4 places :
Symmetric choice reduction at 1 with 4 rule applications. Total rules 23 place count 1507 transition count 1929
Iterating global reduction 1 with 4 rules applied. Total rules applied 27 place count 1507 transition count 1929
Discarding 1 places :
