I'm reserving Riesel base 4 k=13854, 16734, and 19464 for further testing up to about n=250K base 4. I'll sieve to n=500K and leave my files for others if no primes are found on one or more of the k's.
It will also be the same k's for Riesel base 16. Karsten, this also means I'll be reserving k=6927 and 8367 for the Riesel base 2 oddn conjecture. Gary

Sierp. Base 6
Sierpinski Base 6 k=172257 finished up to n=100K. I'm releasing this k. lresults attached for n=30K100K.

Let k=2m and let n=q 2m*4^q1 = 2m*2^(2q)1 = m*2^(2q+1)1 Hence where the base is 4 and k=2m, then where the base is 2, n must be 2q+1; hence odd. In this case, k=13854 and k=16734 base 4 equate to k=6927 and k=8367 base 2 oddn. It's surprising how tricky it has been to keep all of our reservations clean and consistent across all bases without stepping on one another; namely the bases that are powers of 2. Edit: One more requirement...the k base 4 cannot be divisible by 4 in order to 'reduce' to a base 2 oddn k. The evenn and oddn conjectures have a requirement that the k must be odd and divisible by 3 or...as shown on my pages k==3 mod 6. Gary Last fiddled with by gd_barnes on 20080126 at 10:12
