My mate Phil Carmody has run our really prime number from 173,000 to 185,000 and found two primes. This makes now an impossibly rich 166 primes for this k*2^n+1 sequence.
It is interesting that since n got larger than 100,000, there are no fewer than 20 primes discovered up to n=260,000. Here they are: 104186 105283 107911 122428 123760 125392 126478 129152 129850 137749 172113 174521 184521 202474 206409 214727 226714 231290 240057 243709 I wonder how many there are before n=1 million?
