Robert, Your slip is showing again.

Exactly as I tried to point out to you, you were either disallowing
voters to rank only two candidates or to rank all three.  I see I was
correct and you are disallowing voters to rank only two candidates and
have, as Abd ul also pointed out to you, left 3 choose 2 or 6 possible
choices out of your list.

Unfortunately for your system of disallowing voters to rank only two
choices, US courts would rule that any such ballots where voters rank
only two choices as legal votes that must be counted, so you cannot
have a voting system in the US which disallows those choices.

Robert I just proved you wrong, as did Abd ul earlier.  So please try
again if you think your other formula is correct, because
mathematically provably both your formulas are obviously incorrect to
any election methods expert on this list or any mathematician or
probabilist, not just to me.

Reality is a really nice place Robert. I invite you sincerely to join
us in the real world.
