K-NARAYANA SEQUENCE SELF-SIMILARITY
Résumé
This paper introduces self-similarity inherent in planar Milich centered flip graphs derived from the Narayana sequence. We show that selfsimilarity found in a Narayana sequence yields a connected spanning subgraph with a centered flip. This paper has several main results (1) Every Narayana sequence constructs a flip graph, (2) Every Narayana sequence is self-similar and (3) Every Pascal 3-triangle has a free group presentation.
