[B]Keller[/B] Forgive me :bow: instead to reply to your post I pressed "Edit", deleted your post and typed in my reply. You said you would like to cancel k=195 because it has a listed prime at n=311k and work on k=231 in the 200-400k range instead, is that right? I'm not sure is this the k you mentined.

Yes I would like to work on k=231 200000<n<400000 ;)

PS: Forgiven ;)

ns from 200000 to 210000
 

I have checked & completed the following k values from 200000 to 210000:

93, 95, 99, 129, 131, 133, 135, 137, 139, 141, 143, 145, 147, 149, 151, 153, 163, 165, 167, 219, 221, 223, 227, 235, 237, & 239, and found only 93*2^203728-1 and 93*2^205158-1 prime.

I am continuing with 107, 115, 169, 173, 175, 177, 179, 181, 185, 187 & 233 from 200000 to 210000.

update, 115 & 125
 

I have completed 115 & 125 from 200000 to 210000, no primes.
I am also done with 243 at 230000.

I'm reserving k=247

A status update:

k=9, at 801k. No new primes since 503k.
k=33, complete to 500k.
k=105, complete to 500k (prime for n=[B]484658[/B] and n=[B]472430[/B])
k=117, at 438k. No new primes.
k=129, at 253k, n=[B]214985[/B] is prime!

status k=11 and k=29
 

This is my status update:

k=11, at n=1M, no new primes.
k=29, at n=1.15M, no new primes.

Continuing both...

Reserving k=237 from 210k to 500k
and k=241 from 230k to 500k

k=247 is done to 400k and is available - no prime found.

reserve 91
 

Reserving 91 from 210000 to 300000.
