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 formed his own band in West Memphis, Arkansas, in 1948, billing himself as "The Howlin' Wolf". He began broadcasting on radio station KWEM in West Memphis, and was heard by Sam Phillips who signed him for Memphis Recording Service. He recorded "How Many More Years" at the MRS studio at 706 Union Avenue, Memphis, Tennessee, in or about July 1951, singing and playing harmonica with a band comprising (probably) Ike Turner (piano), Willie Johnson (guitar), and Willie Steele (drums). The repetitious bass-string boogie line resembles the one played in the traditional blues standard "Forty-Four". The record's original A-side, "Moanin' at
