Abstract: Many objects in nature have symmetry. Orb web spiders, for instance, create nearly perfect circular webs. Snowflakes have 6-fold radial symmetry, and humans have bilateral symmetry. The set of symmetries of a fixed object form a (mathematical) group, which is a set with a binary relation that is closed, associative, and has an identity element and inverses. Looking at the situation in reverse, every group describes some set of symmetries. Thus, the question arises: for any finite group G, is there an object whose group of symmetries is G? We will answer this question using tools from graph theory.
