Current status Multi Reservation 4: The current nmax = 3,100,000 as of 2020-11-12
Date start 2010-10-24
k-values 35 - 111
n-range 1000000 -
Sieve File:RPS Megabit Drive 1 sieve.zip

2010-10-24: k = 51, 57, 61, 65, 69, 87 for n > 1,000,000
2011-01-26: adding k = 47, 53 for n > 1,000,000
2014-08-12: removing k = 51, 69 for n > 2,500,000
2014-08-12: adding k = 35 for n > 2,520,000, k = 37 for n > 2,500,000 only n != 1 mod 10, k = 103 for n ≥ 2,550,223, and k = 111 for n ≥ 2,601,487
currently k = 35, 37, 47, 53, 57, 61, 65, 87, 103, 111
