Theory

5041/5040 represents the difference between 72/71 and 71/70; therefore tempering this comma out splits their product, 36/35, in two; as 36/35 is the ratio of 6/5 to 7/6, tempering out this comma also splits 7/5 in two, by equating 84/71 to 71/60. It is also a solution to Brocard's problem, n! + 1 = m^2, for which there are only three known answers: 25/24, 121/120, and this.
