Reserving S155

...a lot of time will be wasted!
 

S155 sieve is the prime example of how bad can algebraic get you.

Who sieved this?!
It contains ~19% patently composite values! :gah::gah::gah:

4*155[SUP]4m[/SUP] + 1 = (2*155[SUP]2m[/SUP] - 2*155[SUP]m[/SUP] + 1) * (2*155[SUP]2m[/SUP] + 2*155[SUP]m[/SUP] + 1)
