MMA Math Fails: Every time MMA math failed in the UFC

According to MMA math, if fighter A beats fighter B, and fighter B beats fighter C, then fighter A should beat fighter C. We look at the sequence of fighters that B beat and then the fighters that those fighters beat and so on. If a fighter in that sequence beat fighter A, MMA math has failed.

Input two fighters A and B where A beat B and we will tell you if MMA math works for this example. If it doesn't, we will show you the shortest sequence of fighters needed to show that MMA math fails.
