  2. The construction of an n/17 angle, which this procedure builds on, is more mathematically impressive, if less pretty.  :)

  3. John Dethridge Ah, yes I'm sure you are talking about Gauss's constructable 17-gon. From wikipedia(https://en.wikipedia.org/wiki/Heptadecagon):  "This proof represented the first progress in regular polygon construction in over 2000 years.." Amazing, that and the constructions are just so horribly convoluted. It's fantastic. https://en.wikipedia.org/wiki/File:HeptadecagonConstructionAni.gif
