This Demonstration makes use of the following table of recipes to create frieze functions, represented by series of the form , with complex coefficients . Let represent a half-turn, and perpendicular mirror symmetries, and a glide reflection along the axis.[more]
The functions used here are truncated to
according to the rules. For example, gives
and there would be four interior terms in the functions for and .
Only two copies of a unit cell are shown.[less]
The recipes are taken from [1, p. 59].
