Did you know?
In mathematics, a frieze or frieze pattern is a two-dimensional design that repeats in one direction. Such patterns occur frequently in architecture and decorative art.

Figure 7 shows an example in which we created a mosaic-like image by stamping white and grey squares on a black background to create one unit of a classic “Greek Key” frieze pattern.
Web19 mrt. 2024 · Frieze patterns, introduced by Conway, are infinite arrays of numbers where neighbouring numbers satisfy a local arithmetic rule. Frieze patterns with positive integer values are of a special interest since they are in one-to-one correspondence with triangulations of polygons by Conway--Coxeter.
