  • 04:2404:24, 19 May 2023 diff hist +814 N SpirolateralCreated page with "'''Spirolaterals''' are a class of polygons, mostly self-intersecting, that generally have a single internal angle and a sequence of edge lengths formed from repetitions of the sequence 1, 2, ..., ''n''. A ''simple spirolateral'' is constructed as follows: draw a 1-unit line segment, turn φ degrees clockwise, draw a 2-unit line segment, turn φ degrees clockwise, ... draw an ''n''-unit line segment, turn φ degrees clockwise, repeat from the beginning...."

Polyominoes are named by size (number of constituent unit squares) using Greek prefixes: size 2 is the domino, size 3 is the trominoes, size for the tetrominoes, etc. For heptominoes and above, polyominoes may have holes and are therefore may not be simply connected polyominoes; some do not consider these valid. The enumeration of polyo..."

Golygons were investigated by Lee Sallows. The smallest golygon has eight sides, and interestingly can tile the plane. A '''golyhedron''' is a non-self-intersecting polyhedron where all ''n'' faces are polyominoes and have areas 1, 2, ..., ''n''. T..."
