(26) T2 (EQUIVALENT)
Initially, performed program simplifications using lexicographic rank functions:
 * Removed transitions 1, 3, 4 using the following rank functions:
    - Rank function 1:
      RF for loc. 5: 1+2*x2
      RF for loc. 6: 2*x2
      Bound for (chained) transitions 4: 2
    - Rank function 2:
      RF for loc. 5: 2*x2
      RF for loc. 6: -1+2*x2
      Bound for (chained) transitions 3: 1
    - Rank function 3:

      RF for loc. 6: -1
      Bound for (chained) transitions 1: 0
