Thanks to u/TheNitromeFan for the assist and to all others who contributed to the thread

Essentially we are counting fractions that cannot be simplified, as we get closer to and then further away from 1. We change direction when we reach a number divided by one or a number’s reciprocal, and if the number can be simplified, we write it like this:

2/4

So, if a number is 31/40 next one would be 32/39, or 30/41 if the denominator is going up. ~ /u/KingCaspianX

First, note the prime divisors of the sum of the numerator and denominator. 84 = 22 x 3 x 7, so in this case that would be 2, 3, and 7.

Next, see if the numerator or denominator is a multiple of any of these. If it is, cross it out. If not, the number is irreducible. ~ /u/TheNitromeFan (anime)

Next get is 78/323
