Information theory shows that the probability of being able to express
any arbitrary large number in any form significantly more efficient
than just showing the digits is vanishingly small.

If it interests anyone, I am slightly curious to find out a few
pandigital
primes in bases 8, 12, 16, 20, 36. I just got done adding

There
are other calculations I'm much more interested in, but I have to admit
I do
care a tiny bit to know the answer to this one. There is also the
interesting issue of representing such large numbers in a compact
manner. In
the case of the third vigesimal Smarandache-Wellin prime, I searched
long
and hard for a concise way to express it in the form x^y - r, but to no
avail.
