<p><b>New page</b></p><div>[[File:1-3-5-7-9-13_Eikosany.png|thumb|Circle diagram.]] The second simplest possible [[eikosany]]. This creates a scale of 1 21/20 13/12 9/8 91/80 7/6 39/32 13/10 21/16 7/5 117/80 3/2 91/60 63/40 13/8 273/160 7/4 9/5 91/48 39/20, with steps of 21/20 65/63 27/26 91/90 40/39 117/112 16/15 105/104 16/15 117/112 40/39 91/90 27/26 65/63 21/20 40/39 36/35 455/432 36/35 40/39. With several large steps around its line of symmetry and three microsteps that blur into their neighbours, this is definitely more uneven than the simplest eikosany, but still has more than enough perfect fifths and major thirds that you can compose non-xenharmonic sounding music using the right subset of it. <br />
