- This depends on the interpretation that if there is a tie for one
- place, then all of those tied win that place and the next place
- is awarded to the next one down. In other words, the turtles
- finished 1-2-2-2-2-3.
-
- I don't agree with this -- I would consider Frank to have finished
- 6th overall in this ranking and would thus not be awarded a medal
- (no bronze medal to be awarded when multiple silvers given out).
- Isn't this how the Olympics do it when there is a dead heat?
-
- The only finishes that I would consider to allow every turtle a
- medal are: 1-2-3-3-3-3, 1-1-3-3-3-3, 1-2-2-2-2-2, and 1-1-1-1-1-1.
-
- I come up with 5 possible race outcomes; 7 combinations of which satisfy
- the restriction that no turtle finish the same in both races. Three of
- these combinations give each turtle a medal under the "loose" tie policy,
- but no combination satisfies the tighter tie policy. (Also, no combination
- satisfies the interpretation with medals for each race.)

- Race outcomes:
-
- A C D B F E
- A E D B F C
- D E F A B C
- E A B D C F
- E D A F C B
-
- Combinations:
-
- E A B D C F
- A C D B F E A gold B/C/D/E silver F bronze?
-
- E A B D C F
- A E D B F C A/E gold B/D silver?/bronze? C/F bronze?
-
- D E F A B C
- E D A F C B D/E gold A/F silver?/bronze? C/B bronze?
