This directory contains (besides this README file) 
the following files (all files are plain ASCII files)

1) prim2_16hex.txt       9K

   The odd primes < 2^16 are stored in this file
   as a bit vector of length 2^15, where the n-th bit
   is set iff 2n+1 is prime. This bit vector is
   represented as a sequence of 2^12 = 4096 bytes
   in hexadecimal notation.

2) prim10_050.txt	13K

   This file contains a list of all primes p with
   10^50 - 100000 < p < 10^50 + 100000

3) prim10_100.txt	6K

   This file contains a list of all primes p with
   10^100 - 100000 < p < 10^100 + 100000

4) prim10_200.txt	3K

   This file contains a list of all primes p with
   10^200 - 100000 < p < 10^200 + 100000

5) prim10_400.txt	1K

   This file contains a list of all primes p with
   10^400 - 100000 < p < 10^400 + 100000
