RPS 10th Drive: Back to the Low-Weights
 
Parallel to the 9th Drive we are starting a low-weight drive with 128 Ks, 10000 < k < 35000, all of them having Nash weights less than 300 and are (hopefully) not yet been tested by others:

10781, 10963, 11347, 11519, 11533, 11729, 11953, 12007,
12097, 12191, 12373, 12517, 12749, 13297, 13483, 13511,

16447, 16543, 16573, 16829, 17021, 17113, 17369, 17411,
17467, 17579, 17977, 18103, 18209, 18607, 18727, 18869,
19117, 19121, 19259, 19507, 20017, 20143, 20381, 20399,

32713, 32789, 32887, 33373, 33403, 33419, 33457, 33569,
33937, 34169, 34183, 34297, 34409, 34631, 34679, 34693.

All candidates were initially sieved to p=3.5T. The range of n is 400k-2M, which means that eventually we should find some megabit primes in this drive!

Happy hunting!

taking 410-412

Kosmaj 2009-05-12 12:07

Taking 412-414.

BTW, we'll make reservations by K available soon, for example you can reserve your favorite K from the list above all the way from n=400k to n=2M. We have to do more sieving for that, so most likely it will be from n=500k.
