hi,
cksieve v1.1.0 gives out a warning  what does it means? Code:
cksieve P20e10 i ck.in cksieve 1.1.0  A sieve for Carol (b^n1)^22 and Kynea (b^n+1)^22 numbers. Read 16432 terms for (74^n+/c)^22 from ABC file `ck.in'. cksieve 1.1.0 started: 3 <= n <= 99999, 60000000000 <= p <= 200000000000 p=77153080019, 141204 p/sec, 150 factors, 12.3% done, 0 sec/factor, ETA 18 Apr 08:19 WARNING: 393216 is not a root (mod 77309411329) p=81621680057, 141347 p/sec, 190 factors, 15.4% done, 0 sec/factor, ETA 18 Apr 08:19

Incidentally, that output also show another bug. The factor removal rate is always "0 sec/factor".

...and the ETA seems way off. Or it may be in the wrong timezone (but not UTC, as one could immediately expect).

ETA is fine. It is in local timezone. It is the p/sec that is quirky. I believe it is counting actual p's being processed, rather than the prange being processed (i.e. if it crunched from p=1e9 to p=2e9, it counts it as pi(2e9)pi(1e9) p's processed rather than a range of 1e9 processed).

In the first post I updated to fix the factor removal rate.

Step 1. We can submit e.g. (40^40778+1)^22  as (40^40778+2)*40^407781 Step 2. Submit for PRP test. Because it has a ...1 form, N+1 test is also run (or at least I thin this is how it happens). Then we can query for (40^40778+1)^22 and because this is a shorter form it sticks. And it shows as a P.
