My work on filling in gaps for (near-)Woodall k's has reached n=300k. Three primes were found:
  • 8508301*2^261263-1
  • 1195203*2^262935-1
  • 8508301*2^296247-1

A prime for k=197673 was found earlier.

The list of k's tested to n=300k is:
  • 197673
  • 251749
  • 582833
  • 586085
  • 665127
  • 938237
  • 1183953
  • 1195203
  • 1268979
  • 1467763
  • 8508301

Updates will be posted to Prime-Wiki shortly.

I'm also reserving k=1993191 (the latest near-Woodall k) for n < 3986382.
