Breaking a long drought for new primes on the 6th drive:

733*2^632387-1 is prime

Edit: Karsten, I just noticed this: This is the 5th lowest weight k in the 6th drive and its first prime since n=272251! Interestingly for its weight of just 407, it now has a surprisingly large # of primes: 13.

After a nearly n=14K range without a new prime in the 6th drive, it scores its 2nd one in an n=1500 range:

777*2^633901-1 is prime
