PL> The last time I looked at these numbers is a looong time ago, but at
least
PL> the following questions were unsolved:
PL> - given X, is there a quick way to determine its perfectness ?
PL> - is the number of perfect numbers finite ? If not, what is its
distributio
PL> - are all perfect numbers even ?
(finite?) Since you are dealing with an infinite range,
x - a goes to infinity as x goes to infinity. (where x is the
range of numbers and a is the number of non-perfect numbers)
(not a proof, but a logical assumption)
(quick determination?)
Are any odd numbers perfect? Can you represent the definition
of "perect" using a formula? Do all perfect number end in a 6 or 8?
p(x) = (Ex) a + b + c +...+ n = x
(Ex) a % x = 0, b % x = 0, c % x = 0,...,n % x = 0
where p(x) = perfect nuber
(Ex) = there exists an x (variable)
a,b,c,...,n = constants
% = modulo
This PLF does not explicity state that a,b,c,...,n are the only
divisors of x.
