I&#39;m kinda into polyhedra recently, after reading some math stuff about them a few weeks ago, lol. Turns out you can define a group structure on a topological space by approximating it as a simplex (structure of glueing polyhedra together) and introducing a concept of &#34;orientation&#34; and a mapping from higher dimensions to the borders of the polyhedra, called the homology groups.</html></oembed>
