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 Could an Angel Break My Heart of the song has the storyline laid out a little differently, with Babyface singing back to her and duetting with her from the second verse. Babyface's vocals replace Kenny G's saxophone parts. This CD has an error in the tracks. Despite being listed in this way the two instrumentals have been put on in the reverse order. This can be heard clearly as Kenny G's saxophone parts are present on track four and absent in track three, whereas in the vocal versions of the song, this is quite the opposite.
