I believe this page to be in error:
(consider primes of form 6660000000000....00000000000049, of which there are
infinitely many)

Quite true. For example, the sentence "The empty string is a subsequnce of
of every string." contains two typographical errors.

So what? Did you read their definition of substring (subsequence)?

Jeffrey,
I've now looked at your paper.
The first mistake (I suspect therer are other very similar later) occurs
with the fifth sentence of Case 1b. " Thus we may assume... and either zero
or one 8."
z can perfectly well contain 3 or more zeroes - your assumption is
completely arbitrary. It's not actually _wrong_ except in the context that
you are trying to generate a minimal list. I could easily give you a general
minimal list for any set (1,2,3,4,5,6,7,8,9,0). Or, to put it another way -
why do you bother to draw the distinction between the larger numbers on your
list with varying numbers of the same digit - just quote each digit once and
leave it at that - _or_ appreciate instead that there are infinitely long
strings of digits that are equally prime and equally valid.

It's not really your fault - Lothaire's paper is obviously clearly garbage
too...

Right. But, last time I checked, 1, 4, 6, 8, 9, and 0 are not primes.

Sad, sad, sad!

Those aren't primes.

Are you referring to

M. Lothaire,"Combinatorics on Words"?

That's a book, not a paper, and is not "clearly garbage".
