| Writing (prime(i))^j as i:j, we have the following table:
Primal Functions and Functional Digraphs for a(0) to a(5)
` ` ` 2 = 1:1 ` ` ` ` ` ` || 1 -> 1 (infinite loop)
` ` ` 1 = { } ` ` ` ` ` ` || 1
` ` ` 3 = 2:1 ` ` ` ` ` ` || 2 -> 1
` ` `20 = 1:2 3:1 ` ` ` ` || 3 -> 1 -> 2
` ` 756 = 1:2 2:3 4:1 ` ` || 4 -> 1 -> 2 -> 3
`178200 = 1:3 2:4 3:2 5:1 || 5 -> 1 -> 3 -> 2 -> 4
