I had R470 (as well as R471) continued to n=75K, but didn't make a note of it.
With 83*470^61902-1 prime, there's one [I]k[/I]=137 left.
Re-reserving to n=100K.

Here is a clarification that I got from Serge in a PM on his status for R470 and R471:

[quote]
Briefly, R471 is of course slow (with 3k's!) and I only intend to finish the 75K that I reserved. Tests are taking 1100s for R471 now. It is at 67K; no primes.
R470 also takes 800-900s per test but with the sudden prime I will take it to 100K.

S363 with CK=64 is proven with a highest prime of 48*363^4283+1.

Also reserving S320 with CK=106 to n=25K.

Whilst work on R603 is paused (see question in relevant thread), I'll take S425 (conj k=70) out for a spin.
Two k remain at n=2500, (k=8 and k=70) (actually, do I need to test k=70? I'm having a daft moment here :P)
Reserved to n=25K.

paleseptember,

You do not need to test k=70, since it is the CK.

Thank you for your time
