global look

drawing: Goossen Karssenberg
  • The polygons between the pointed figures seem irregular but at a closer look one notices some regular heptagons.
  • One can see clearly that the pattern has got an axis of symmetry.
  • It’s possible to identify a unit repeat.
  • An underlying polygonal pattern consists of just two different hexagonal figures.
  • In next pages we’ll examine these hexagons and how they fit into the unit repeat.
