WebJun 7, 2024 · One of the first properties of frieze patterns is that every quiddity sequence of a closed integral frieze contains at least two entries equal to 1. Theorem 2 gives a geometric reason for this, since every triangulation contains at least two triangles that are peripheral, i.e., for which two edges are boundary segments.
