Hi
Here is all the information which I have about sieves:
k=33661 is sieved by Louie up to 1000G.
Almost all of the k values are sieved by approx. 80 G by Phil Carmody and approx. up to 200G by Joseph Arthur.
I have attached the final result of k=4847 sieve. It is sieved up to 96G by Phil and then up to 208G by Joseph.
You can continue it using Paul Jobling's NewPGen and then report the result to Louie to use it.
