a prime is a number who divides by itself AND one ... including the
number one in the set starts off all sorts of nasties when looking at
prime conjectures/proofs... I have no time to explain, but you should
find this easily on the net...
every prime divides by exactly 2 elements of the integer field, if you
include the identity itself, this structure breaks down...
hope this helps
