The Three-twist knot, also known as the trefoil knot, is one of the simplest and most well-known types of nontrivial knots in topology. It can be visualized as a loop with three twists in it, and it is often represented as a closed curve that can be drawn in three-dimensional space without self-intersecting, yet cannot be untangled into a simple loop without cutting it.
