Frieze pattern
|
|
In geometry, a frieze pattern is any of a number of tilings that repeat an object through a horizontal translation, classified by what they contain. There are a total of seven possible basic frieze patterns, comprising:
- T (translation only)
- TG (translation and glide reflection)
- THG (translation, horizontal line reflection, and glide reflection)
- TV (translation and vertical line reflection)
- TR (translation and 180-degree rotation)
- TRVG (translation, 180-degree rotation, vertical line reflection, and glide reflection)
- TRHVG (translation, 180-degree rotation, horizontal line reflection, vertical line reflection, and glide reflection)
