Division 15 — Mechanical/Plumbing; Division 16 — Electrical; DIVISION 17 - MASTER FORMAT RELATED SPECS, NONCONFORMING TO THE ABOVE CSI SECTIONS. All spec divisions higher than 16 are placed in Division 17 - Others. Also use Division 17-Others for any spec-shaped material not easily classified (e.g., geotechnical, pre-bid notes, etc.)
There are three regular star polygons, {16/3}, {16/5}, {16/7}, using the same vertices, but connecting every third, fifth or seventh points. There are also three compounds: {16/2} is reduced to 2{8} as two octagons , {16/4} is reduced to 4{4} as four squares and {16/6} reduces to 2{8/3} as two octagrams , and finally {16/8} is reduced to 8{2 ...
Clusters of planigons which cannot tile the plane. Note the 8-cluster of V3.8.24 and the 10-cluster of V3.10.15 imply overlaps for the 24-gons and 15-gons, respectively. Also, V4.5.20 and V5 2.10 can generate lines and curves, but those cannot be completed without overlap.
A regular digon has both angles equal and both sides equal and is represented by Schläfli symbol {2}. It may be constructed on a sphere as a pair of 180 degree arcs connecting antipodal points, when it forms a lune. The digon is the simplest abstract polytope of rank 2. A truncated digon, t{2} is a square, {4}. An alternated digon, h{2} is a ...

The first QIC tape format was the 5 + 7 ⁄ 8 inches (150 mm) by 3 + 7 ⁄ 8 inches (98 mm) Data Cartridge (DC) format with two internal belt-driven reels and a metal base. The original product, the DC300, has 300 feet of tape and holds 200 kilobytes. Various QIC DC recording formats have appeared over the years, [2] including:
