The technique of distinguishing one knot from another by coloring arcs and applying some basic modular arithmetic is part of most standard undergraduate knot theory classes. When we study n-colorability, we are usually only interested when n is a prime number. But what if n is composite? What can we say then?
通过给弧着色和应用一些基本的模块算术来区分一个结和另一个结的技术，是大多数标准本科结理论课的一部分。在研究 n 可着色性时，我们通常只对 n 是质数时感兴趣。但如果 n 是合数呢？我们又能说什么呢？
