Every number in an (e, n) is there because there exists a number in (e, 1) that is a*n. If that a is a prime, then it should start a new "chain" in the n records. Take for example (0,
8). It contains 4 chains based on the initial map generation program by VCQ. It's only 4 chains, because we have a limited generation of numbers in the initial map program. If
you extend this further then you should see even more chains in (0, 8)
