The range of exponents is denoted by n_min <= n <= n_max where n_max=1M while n_min for respective Ks is given below. k=213, n_min=250k k=237, 249, 261, 273, 279, 291, n_min=260k k=135, 267, n_min=300k k=129, n_min=398k k=57, n_min=400k k=117, n_min=438k k=285, n_min=470k k=51, n_min=475k With exception of k=129, for each k, n_min in the drive equals previously achieved n_max from our stats page. In case of k=129 we are leaving a 253-398k gap to be double-checked later. [It was most likely checked by Jeffrey who reported 5 primes, but there is no way to know because he hadn't reported the range he processed. Volunteers for double-checking are welcome.] Sieving has been done by amphoria, Larry, Thomas, segmtfault, Battlemaxx, and me. And recently by BlisteringSheep. Happy hunting!
