运行这段代码确保可以求幂（忽略我之前提到的 bug），这样就完成了一半的工作。

Running this code verifies that exponentiation works (modulo the bug I mentioned earlier), so half of the battle is now complete.

左半正规纯正半群是幂等元集形成左半正规带的纯正半群。

A left seminormal orthodox semigroup is an orthodox semigroup whose idempotents form a left seminormal band.
