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, Now Both Sides, Now "Both Sides, Now" is one of the best-known songs of Canadian singer-songwriter Joni Mitchell. First recorded by Judy Collins, it appeared on the U.S. singles chart during the fall of 1968. The next year it was included on Mitchell's album "Clouds" (which was named after a lyric from the song). It has since been recorded by dozens of artists, including Frank Sinatra, Willie Nelson and Herbie Hancock. Mitchell herself re-recorded the song, with an orchestral arrangement, on her 2000 album "Both Sides Now". This version was featured in the film Love Actually (2003). In 2004, "Rolling Stone"
