[The following post is about 281*2^6288981, a prime found by Cruelty in December 2007.]
Cruelty, a nice and important prime because k=281 was the only k<300 with no primes with more than 100k bits!
Next target: 200k bits, there are 4 Ks with no primes larger than 200k bits: k=109, 221, 233, and 283. All reserved by you !! The one with the minmax prime is k=221: n=104846.
