聽說這兒好多數學迷，數學牛人。

能不能請你們為我的朋友解答一道數學題？據說要求15分鍾內就可以解答。

先謝謝了。

given permutation p = (3 4 1)(2 5) and q = (1 4 5 2), both in cycle notation and with permutation product from right to left, we can see that p q and q p result in a 3-cycle. Is this an accident ? If not, what are the properties causing it ?
