It's World Cup season (or at least it was when this page was created)!
The World Cup is an international football/soccer tournament that happens every 4 years. Countries put their international teams together in the years between tournaments and qualify for the tournament based on their performance in other international games. Once a team has qualified they are put into a group with 3 other teams.
For the first part of the World Cup tournament the teams play in "group stage" games where each of the four teams in a group [[wp:Round-robin tournament|plays all three other teams once]]. The results of these games determine which teams will move on to the "knockout stage" which is a standard single-elimination tournament. The two teams from each group with the most standings points move on to the knockout stage.
Each game can result in a win for one team and a loss for the other team or it can result in a draw/tie for each team.
:::* A win is worth three points.
:::* A draw/tie is worth one point.
:::* A loss is worth zero points.
;Task:
:* Generate all possible outcome combinations for the six group stage games. With three possible outcomes for each game there should be 3<sup>6</sup> = 729 of them.
:* Calculate the standings points for each team with each combination of outcomes.
:* Show a histogram (graphical, ASCII art, or straight counts--whichever is easiest/most fun) of the standings points for all four teams over all possible outcomes.
Don't worry about tiebreakers as they can get complicated. We are basically looking to answer the question "if a team gets x standings points, where can they expect to end up in the group standings?".
<small>''Hint: there should be no possible way to end up in second place with less than two points as well as no way to end up in first with less than three. Oddly enough, there is no way to get 8 points at all.''</small>

There might be a more elegant way of expressing this.
<
outcome=: 3 0,1 1,:0 3
pairs=: (i.4) e."1(2 comb 4)
standings=: +/@:>&>,{<"1<"1((i.4) e."1 pairs)#inv"1/ outcome</
Here, standings represents all the possible outcomes:
<
729 4</
Of course, not all of them are distinct:
<
556 4</
With only 556 distinct outcomes, there must be some repeats. Looking at this more closely (gathering the outcomes in identical groups, counting how many members are in each group, and then considering the unique list of group sizes):
<
1 2 3 4 6</
Some standings can be attained two different ways, some three different ways, some four different ways, and some six different ways. Let's look at the one with six different possibilities:
<
4 4 4 4</
That's where every team gets 4 standing.
Line 678 ⟶ 754:
How about outcomes which can be achieved four different ways?
<
6 6 3 3
6 3 3 6
Line 684 ⟶ 760:
3 6 6 3
3 6 3 6
3 3 6 6</
Ok, that's simple. So how about a histogram. Actually, it's not clear what a histogram should represent. There are four different teams, and possible standings range from 0 through 9, so we could show the outcomes for each team:
<
27 81 81 108 162 81 81 81 0 27
27 81 81 108 162 81 81 81 0 27
27 81 81 108 162 81 81 81 0 27
27 81 81 108 162 81 81 81 0 27</
Each team has the same possible outcomes. So instead, let's order the results so that instead of seeing each team as a distinct entity we are seeing the first place, second place, third place and fourth place team (and where there's a tie, such as 4 4 4 4, we just arbitrarily say that one of the tied teams gets in each of the tied places...):
<
0 0 0 1 14 148 152 306 0 108
0 0 4 33 338 172 164 18 0 0
0 18 136 273 290 4 8 0 0 0
108 306 184 125 6 0 0 0 0 0</
Here, the first row represents whichever team came in first in each outcome, the second row represents the second place team and so on.

This example codes results as a 6-digit number in base 3. Each digit is a game. A 2 is a win for the team on the left, a 1 is a draw, and a 0 is a loss for the team on the left.
