It looks a little better at
than in the mail. It's still cryptic without an explanation but I figured
out what it shows. I didn't figure out any significance though.

The count of each digit in a prime is given. It assumes 6-digit
primes with leading 0's allowed and counted, but not written.

"4 1 0 1 0 0 0 0 0 0 3001" means the prime 3001 has 4 '0'
(when written as 003001 with 6 digits), 1 '1', 0 '2', 1 '3', 0 '4',
0 '5', 0 '6', 0 '7', 0 '8', 0 '9'.

For unknown reasons, the primes appear to be sorted in reverse
lexicographical order of their digit counts. Primes with the same
digit count like {31, 3001, 13, 103, 100003} are also sorted
internally in reverse lexicographical order (without assuming
