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)

That is one hel heck of a dandy hint!!     -- Gerard Schildberger (talk) 18:56, 11 April 2019 (UTC)
