Why NeRDs_360360?
Why did I choose 10^36036010^k1?
360360 = 2*2*2*3*3*5*7*11*13 For small primes p, 10^((p1)*a)==1 (mod p), and so 10^36036010^k1 is not divisible by p. Consequently, after sieving, there is about 15% of the range left and we expect to find about 3 primes in the provable range k=90090360360. 
It would have been better to chose a>1290000*log[SUB]10[/SUB]2 for 10^a10^k1. With a=360360, the found primes will be swept away in about a year by the TwinGenial deluge. a=17#, perhaps?

What's the total number of candidates left after sieving? 
42320 candidates were left in the range 90000360360.
Chuck Lasher is crunching 3/19 of this. Thomas, you are crunching 1/19. I crunched some. The rest was put up, ready for others to crunch  1 or 2 weeks per file folks.

These may be "swept away" from the top5000, but they should stay on the nearrepdigit table. I have exponents 388080 and 471240 sieved. :smile:
