Octadecagon 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 as a quasiregular truncated enneagon, t{9}, which alternates two types of edges. As 18 = 2 × 3, a regular octadecagon cannot be constructed using a compass and straightedge. However, it is constructible using neusis, or an angle trisection with a tomahawk. The following approximate construction is very similar to that of the enneagon, as an octadecagon can be constructed as a truncated enneagon. It is also feasible with exclusive use of compass and straightedge. The "regular
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
