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
How Many More Years Midnight", described by Phillips as "the most different record I ever heard", was probably recorded at a different session. Phillips had not yet set up Sun Records and regularly leased his recordings to the Chess label in Chicago. The record was issued as Chess 1479 on 15 September 1951, with "Moanin' at Midnight" as the A-side and "How Many More Years" as the B-side. "Moanin' at Midnight" entered the R&B chart on 10 November 1951, and was followed four weeks later by "How Many More Years", which became the more popular side and rose to no.4 on the chart. The
