Re: Possible base-20 numeric system

As Danny remarks below, Welsh and French use a "bizarre" base-twenty system
of counting that is Celtic in origin.

One, two, three, four, five, six, seven, eight, nine, ten, one on ten, two
on ten, three on ten, four on ten, fifteen (pymtheg, an older version of
"five and/with ten"?), one on fifteen, two on fifteen (un ar bymtheg, dau ar
bymtheg), two nines, four on fifteen, twenty (ugain).  There, we just
counted in traditional Welsh.  Then, for twenty through forty, you repeat.
One on twenty, two on twenty, three on twenty, etc, fifteen on twenty
(35)...  Fifty is "half hundred" (hanner cant).

I find French counting (I lived and learned in Switzerland which switched to
a decimal system) similarly bizarre, and have never fully mastered it.  In
Geneva we said septante instead of soixante-dix; octante instead of
quatre-vingts (four twenties: pedwair ugain in Welsh), and nonante instead
of the hugely cumbersome quatre-vingts-dix.  They do this, IIRC, in Belgium,
too.  I'll admit to having an admiration for the quaint Gallic and Cymric
mixed-base structure (the fifteen, for instance in Welsh), and sort of
lament the simplifications (Welsh has simplified its numbers too: un deg
pump for 15; tri deg for 30 instead of deg ar hugain); so I hope that Danny
can make something even more fiendish than Welsh and French base-twenty
counting.

However, I'm confused.  I thought Simon's remarks were in response to
Trebor's post about a base-twenty counting system.  Does Trebor have the
same aims that Danny does?
