I was basically asking whether elements in a
set
need to share something
in
common.

Other than membership in that set, no!

Then why would they be in a set in the first
place?
Can you provide me with an example of a set whose
elements have nothing in
common with each other, other than the fact that
they
belong to the set?



Okay, let A be the set containing: {The Ford Falcon
on I owned 30 years ago, that oddly shaped cloud just
south of me right now, the number 46, and all prime
roots of the equation 14x^6- 7x^5+ 32x^4- 14x^3+ 7x-
288= 0}

What do those have in common other than they are
are in that set?

FWIW, I think of a Set (or "collection") as a Universe with its on _rules_.

Quite gameish...
