- You must submit your entry by September 2, 2010, 23:59 (sorry, I can't wait until 2011, the next prime year)
- Your submission must be a sequence of decimal digits.
- The number that these represent must be prime (which make up (in order) a prime number. You may use a test like Rabin-Miller, which will be the method used to validate the submission. Note that it is therefore possible for the submission to fail such a test, even if it passed for the sumitter.
- The number must be composed of at least either 155 decimal digits or 512 bits (either will do).
- The winner will be the number which has the highest ratio of any one digit. For example, "23" has a 50% ratio of the digit "2" while 1011 has a 75% ratio of "1"

which has 31 zeros for a ratio of 20%. Obviously, your submission should seek to beat at least this relatively low number.
You can submit as many times as you like, but in order to avoid making me unhappy with you, I suggest waiting until the last minute (or whenever you decide to stop searching) and submit the best result you have by then.
The winner will get a lifetime subscription to this blog and their name prominently featured in the article in which the number is published.
For fun, I'll be writing my own solver in Rakudo Star Perl 6. It won't be very efficient, so I expect it to get seriously trounced, but I'll do it for the fun. Even if I find the best number, I'll publish the best submission from someone else.
