Handy hints
Handy optimization hints: Terms in position n that is a prime number are always the nth prime raised to the (n-1)th power. E.G.
# 1 2 3 4 5 6 7 8 9 10 11 primes 2 3 5 7 11 13 17 19 23 29 31
Term 7 is 17^6 == 24137569. Term 11 is 31^10 == 819628286980801.
and so on.
Non prime odd terms are always a square number. --Thundergnat (talk) 18:53, 11 April 2019 (UTC)
