Octadecagon and 2{9/4} or two enneagrams, {18/6} is reduced to 6{3} or 6 equilateral triangles, and finally {18/9} is reduced to 9{2} as nine digons. Deeper truncations of the regular enneagon and enneagrams can produce isogonal (vertex-transitive) intermediate octadecagram forms with equally spaced vertices and two edge lengths. Other truncations form double coverings: t{9/8}={18/8}=2{9/4}, t{9/4}={18/4}=2{9/2}, t{9/2}={18/2}=2{9}. The regular octadecagon is the Petrie polygon for a number of higher-dimensional polytopes, shown in these skew orthogonal projections from Coxeter planes: Octadecagon An octadecagon (or octakaidecagon) or 18-gon is an eighteen-sided polygon. A "regular octadecagon" has a Schläfli symbol {18} and can be constructed
Both Sides This completed track features an atmospheric drum machine, keyboard sounds (no piano) and vocals by Collins telling a story about a disaster at sea and families left behind. In November 2004, Collins himself commented on the song on the forum of his old official website: ""DEEP WATER TOWN...again I scratch my head and ask how did someone get it... I don't think it was ever released, or am I going slowly senile. It was a pretty song about a disaster at sea, and the families left behind. Obviously one of my more cheerful pre-divorce moments.
