Abstract.A loop of polygons is a planar arrangement of congruent non overlapping regular polygons in which each polygon has a common edge with exactly two other polygons. A loop encloses an equilateral polygon (not necessarily convex or equiangular but we will require it to be not self-intersecting and of positive area) that we will refer to as the window of the loop. We conduct an exhaustive computational search for all loops of polygons or \(n\)-gons for $3 \leq n \leq 10$ and small values of the perimeter of their windows. The stages leading to the generation and display of the loops were implemented in Mathematica.
