Reserving Sierp base 6 k=10107, 13215, and 14505. I'll take them up to about n=60K or until I find primes or get tired of them.
 I may combine them in with team drive 3 after hitting n=60K. Gary |

Riesel base 4 and 16 status on 2 reserved k's
Riesel base 4 k=13854 and 19464 are complete to n=300K. No primes. They are now unreserved.
This means that the same k's on Riesel base 16 are completed to n=150K and are also unreserved. |

After a draft of 10k n’s without primes, there are two in a row:
83988*31^41706-1 is prime 111038*31^42197-1 is prime Jippee That leaves 11 candidates on Riesel 31 (26064 candidates to test upto 100k) |
