Computed a total of 87 stabilizing places and 87 stable transitions
Knowledge obtained : [p0, (X (X p0))]
False Knowledge obtained : []
Property proved to be true thanks to knowledge (Minato strategy)
Knowledge based reduction with 2 factoid took 23 ms. Reduced automaton from 3 states, 3 edges and 1 AP (stutter sensitive) to 1 states, 0 edges and 0 AP (stutter insensitive).
