Original Wikitext content:
One measurement of the complexity of the comma could be the number of prime factors it has, regardless of their magnitude. To calculate the number of prime factors in a [[monzo]], simply take sum of the absolute values of each coordinate. For example, 81/80 i.e. |-4 4 1> would have a factor limit of 4+4+1=9, or, with 2's taken for granted, 4+1=5. =Not yet the right name= I want to speak of a limit on the number of instances of prime factors, not the number of different prime factors. For example, 45 has factors 3, 3, and 5; here, we want to count each 3 separately. =With 2's taken for granted= ==2-factor-limit commas== 16/15 ( / 3 / 5) 33/32 (3 * 11) 65/64 (5 * 13) ==3-factor-limit commas== 25/24 (5 * 5 / 3) 128/125 (5 * 5 * 5) 21/20 (3 * 7 / 5) 26/25 (13 / 5 / 5) 49/48 (7 * 7 / 3) 64/63 ( / 3 / 7 / 7) 256/245 ( / 5 / 7 / 7) 80/77 (5 / 7 / 11) 22/21 (11 / 3 / 7) 40/39 (5 / 3 / 13) 96/91 (3 / 7 / 13) 55/52 (5 * 11 / 13) 1024/1001 (7 * 11 * 13) 512/507 (3 * 13 * 13) 169/160 (13 * 13 / 5) 176/169 (11 / 13 / 13)
