A 2017 ethnomathematics paper to which the authors eral symmetry, as of a leaf or face; (2) rotational symmetry, contributed concludes that the designs on European regional folk dress as of a starfish or composite flower; (3) frieze symmetry, as are highly symmetric and analyzes the symmetry in the costume designs ABSTRACT of 73 European cultures. Also examined are which symmetries are of regularly spaced buds on a branch or the skin of a snake; favored by, for instance, Catholic cultures or mountain cultures. In this (4) space-filling symmetrical patterns, as of honeycombs or article, two of the study’s coauthors summarize its key points and go on pineapples. Around 70,000 BCE, early humans, attracted to explore the neurophysiologic, aesthetic and ethnographic reasons by these symmetries, began producing abstract decorative why humans display symmetry on their regional dress. nonrepresentational symmetrical designs, predating repre- sentational art by 30,000 years.

The three types of planar crystallographic groups are Ro- tational, Frieze and Space-Filling. For a design to possess Rotational symmetry its appearance must be invariant when David A.
