[seqfan] Most absurd seq ever? Commas and "1"s

Hello SeqFans,
please skip this msg if you're not in a joke mood...


P was meant to be the lexico-first seq
showing only primes (and no duplicate
term) where --ahem-- the simultaneous
replacement of every comma by a "1" and every "1" by a comma produces a
seq of non-primes (no duplicates either)!

Indeed (if my hand didn't shiver), P will 
become Q, matching all requirements:


To compare a few terms of P and Q, look here (fixed font recommanded):


I had in mind to create an "absurd" seq,
which would be impossible to program
on a computer... Now I have my doubts...
Now, if someone with computer
skills had the patience to read so far,
and the will to check (and extend) this
non-sense, I would be delighted, of course!
Just in case: if someone writes the said
program, it might be used to compute
9 more seqs -- the ones where the commas
are replaced by 0,2,3,4,5,6,7,8,9 respectively
and vice-versa.
Sorry for the silly symphony, you were warned!
