Stuttering acceptance computed with spot in 594 ms :[(OR (NOT p1) p0 (AND (NOT p2) (NOT p3))), (OR (NOT p1) (AND (NOT p2) (NOT p3))), true, (NOT p1), (NOT p3), p0, (NOT p1), (AND (NOT p3) p0), (OR (AND (NOT p1) (NOT p3)) (AND (NOT p2) (NOT p3))), (AND (NOT p1) (NOT p3)), (AND (NOT p3) (NOT p1)), (AND (NOT p0) p1 (NOT p2) (NOT p3)), false, false, false]
Reduction of identical properties reduced properties to check from 24 to 22
