Hoping Phil doesn't mind me disclosing here some private
correspondence between him an I: Phil ran some tests on a 900cc Duron
on (those damned) Kynea/Carol numbers with the following timings:

PFGW -- 54:77 m
Phil -- 38:56 m

Converting in and out of base 10 is quick on a computer; We should see
a speed up for base 10 numbers such as (trinomial) palindromes and
near-repdigits. Or (trinomial) near-repdigit palindromes ;-)

Phil was interested in forming a team to look for near-repdigit
palindromes. It is a pity that it can not be "primeform e-group" -- we
would not be using PFGW.

It would nice to hear from Phil about this,

Paul
