   This page gives you the information you need to choose a range of
   exponents to test. After choosing a range you must download the
   database and e-mail me so that other searchers do not duplicate your
   work!

   By choosing a range from this section you will be searching for
   Mersenne primes larger than any found thusfar. A Pentium computer will
   take about two to three months to complete this assignment. These
   ranges are not recommended for 486s or Cyrix 6x86 owners.
   
   
   [1]Download the database (137K).
   [2]Pick a range of 200 to 300 numbers. Available numbers are from
   3094600 to 3096100, 3103000 to 3104800, 3105850 to 3111000, 3118230 to
   3119800, 3194400 to 3199200, 3207400 to 3208700, 3222700 to 3232000,
   3232700 to 3233000, 3238200 to 3242700, 3249200 to 3250700, 3251350 to
   3252000, 3252300 to 3254000, 3256200 to 3258000, 3263400 to 3267000,
   3272000 to 3275000, 3278700 to 3280000, 3282250 to 3286000, 3302000 to
   3304000, 3304600 to 3306000, 3313600 to 3316000, 3317400 to 3318000,
   3321100 to 3321400.

                             The BIG Exponents

   You could be the first person to find a 1,000,000 digit prime number!
   However, these exponents take quite a while to test. A 200 MHz Pentium
   computer will take 10 to 20 days to test a single exponent! These
   ranges are not recommended for 486s or Cyrix 6x86 owners.

   [4]Pick about a three month supply of exponents. This will usually be
   a range of 50 to 200 numbers. Available numbers are from 3340400 to
   3400000, 3401000 to 3412000, 3412700 to 3450000, 3452000 to 3461000,
   3465200 to 3469000, 3471000 to 3473000, 3473200 to 3474000, 3476400 to
   3499500, 3501500 to 3654000, 3655000 to 3701000, 3703050 to 3953700,

   Pentiums, 486s, and Cyrixes can be used in factoring Mersenne numbers.
   You won't find any Mersenne primes this way, but your results will be
   used to update the database to help speed up the Lucas-Lehmer testing.

   4664000 to 4694500.
