 * Title            : synthInvN
 * Description      : Toy benchmark for which the result is "p = 1/i | i \in N" but IMITATOR cannot find it because the accumulated constraints grow forever
 * Correctness      : Reachability
 * Scalable         : no
 * Generated        : no
 * Categories       : Academic ; Toy ; Unsolvable
