If I take the (decimal) powers of 0.999 and get bored after 100
trials, I find they _all_ start with a 9 ;-)

Yes. Though they were talking about the exponents...

That's the type
Note that in the set of mersenne prime exponents (so far), the leading
digit 1 (in decimal), turns up 10 times as opposed to the 4.2 times
expected by equal leading digit distribution...
Actually we should expect an excess of smaller leading digits over

I've noticed that with any odd number you can make the formula x^2 -
y^2 = n where n = the odd number and x - y and x + y are factors of n.
I was just wondering if one could use the graph of a hyperbola to see
only the possible integer values of x and y.

In some vague attempt to not take the Benford issue off topic, it's
interesting that numbers 2^n (for all Natural numbers n) follows the
pattern VERY closely,
In the limit as n - infinity, 2^n must follow the law exactly. Almost by
definition.

Maybe it's my imagination, but it seems to me that the factors of the
prime exponent Mersenne numbers start with a 1 more often than a 2 or
3 etc. Are they obeying Benford's law too?
For instance, for the 10 primes from 5003 to 5081, there are 20 known
factors. 10 of
