An amusing side to this is if you look up base in a thesaurus you will find
repugnant as a synonym.

Maybe this does what you want
http://www.research.att.com/~njas/sequences/frac.html
On a higher or more futuristic level though, I think we should be able to
mix letters with
numbers such as 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,10,.. the sequence of hex
numbers. Just
letters for now. Recall, early mathematics was done in words for centuries
before the simplicity
of symbols evolved into the picture. However, in my opinion, it has gone too
much to the
esoteric invent symbols as you go today.

Indeed, if somehow a decree came down that we can only have 100 nice
sequences at any
one time, THAT would be nice.
How often do we discover a sequence and lo and behold find it is already out
there with the
"Atta Boy" nice attached to it. Then if I we notice that our GF is different
we submit a
comment and piggyback on the nice sequence. We all know "nice" is an
evolvement, since most
of the great sequence discoveries of math was made years ago and have long
been documented
in the literature. Perhaps the word nice can go with a star * system similar
to the movie industry.
Eg., ***** = core, **** = nice, *** = good, ** = fair, *=poor.
"Yes, I am opinionated but so is everyone else"
Have a nice day,
Cino
