Star Anagram Detection and Classification
share
A star anagram is a rearrangement of the letters of one word to produce another word where no letter retains its original neighbors. These maximally shuffled anagrams are rare, comprising only about 5.7 They can also be depicted as unicursal polygons with varying forms, including the eponymous stars. We develop automated methods for detecting stars among other anagrams and for classifying them based on their polygon's degree of both rotational and reflective symmetry. Next, we explore several properties of star anagrams including proofs for two results about the edge lengths of perfect, i.e., maximally symmetric, stars leveraging perhaps surprising connections to modular arithmetic and the celebrated Chinese Remainder Theorem. Finally, we conduct an exhaustive search of English for star anagrams and provide numerical results about their clustering into common shapes along with examples of geometrically noteworthy stars.
