The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.
Original Wikitext content:
4L 3s refers to the structure of moment of symmetry scales with generators ranging from 1\4edo (one degree of [[4edo]], 300¢) to 2\7edo (two degrees of [[7edo]], or approx. 342.857¢). The spectrum looks like this: ||||||||||||||~ Generator ||~ Scale ||~ g in cents ||~ 2g ||~ 3g ||~ 4g ||~ Comments || || 1\4 || || || || || || || 1 0 1 0 1 0 1 || 300.000 || 600.000 || 900.000 || 0.000 ||= || || || || || || || || 8\31 || 7 1 7 1 7 1 7 || 309.677 || || || ||= Myna is around here || || || || || || || 7\27 || || 6 1 6 1 6 1 6 || 311.111 || || || ||= || || || || || || 6\23 || || || 5 1 5 1 5 1 5 || 313.043 || || || ||= || || || || || 5\19 || || || || 4 1 4 1 4 1 4 || 315.789 || 631.579 || 947.368 || 63.158 ||= || || || || || || 9\34 || || || 7 2 7 2 7 2 7 || 317.647 || || || ||= Hanson/Keemun is around here || || || || 4\15 || || || || || 3 1 3 1 3 1 3 || 320.000 || 640.000 || 960.000 || 80.000 ||= || || || || || 7\26 || || || || 5 2 5 2 5 2 5 || 323.077 || 646.154 || 969.231 || 92.308 ||= || || || 3\11 || || || || || || 2 1 2 1 2 1 2 || 327.273 || 654.545 || 981.818 || 109.091 ||= Boundary of propriety (generators larger than this are proper) || || || || || 8\29 || || || || 5 3 5 3 5 3 5 || 331.034 || 662.069 || 993.013 || 124.138 ||= || || || || || || || 21\76 || || 13 8... || 331.579 || || || ||= || || || || || || || || 34\123 || 21 13... || 331.707 || || || ||= Unnamed golden temperament || || || || || || 13\47 || || || 8 5 8 5 8 5 8 || 331.915 || || || ||= || || || || 5\18 || || || || || 3 2 3 2 3 2 3 || 333.333 || 666.667 || 1000.000 || 133.333 ||= Optimum rank range (L/s=3/2) || || || || || 7\25 || || || || 4 3 4 3 4 3 4 || 336.000 || 672.000 || 1008.000 || 144.000 ||= || || 2\7 || || || || || || || 1 1 1 1 1 1 1 || 342.857 || 685.714 || 1028.571 || 171.429 ||= || There are two notable harmonic entropy minima: [[Kleismic family|hanson/keemun]], in which the generator is 6/5 and 6 of them make a 3/1, and [[Starling temperaments|myna]], in which the generator is also 6/5 but now **10** of them make a 6/1 (so no 4/3's or 3/2's appear in this scale).
