摘要:
In this paper we present and prove a simple but non-obvious topological fact. This fact is so simple and funny that can be included in a collection of puzzles or suffested as a problem for a school mathematical tournament. The aim of this article is to present a method by which this fact, in spite of its unserious character. can be applied to produce new non-trivial group-theoretic results.
