*For the of the UEFA Champions League, the eight group winners have to be drawn against a runner-up of another group. The number of possible outcomes is !8 = 14,833. In reality, the actual number is almost always smaller, since teams of the same association cannot be drawn against each other.
*In the group stage of the , teams of different confederations, or sometimes two teams, play another. The number of possible matches is currently equal to 18,994.
*Since there are 211 members, and at most one of the 11 OFC members may qualify for the FIFA World Cup, there are 211C2 − 11C2 = 22,100 possible final matches.
*Ignoring chronological order, there are 10!/5! = 18!!!! = 30,240 possible combinations for a matchday in a 10-team league, such as the CONMEBOL group of the FIFA World Cup qualification.
*The goes over 42,195 s or 42.195 km or 26.22 s.Marathon, ScienceDaily It is equal to 291C2.
*Since there are 211 FIFA members, and at most one of the 11 OFC members may qualify for the FIFA World Cup, there are 211P2 − 11P2 = 44,200 possible combinations for the two highest ranked nations.
*In some countries, there are s involving 11 matches. The number of possible combinations is 311 = 177,147.
*In some countries, there are s involving 12 matches. The number of possible combinations is 312 = 531,441.
*For each match of certain international football tournaments, such as the FIFA World Cup, each national team has to choose one out of three, and 10 s out of 20. The number of possible combinations is 3 × 20C10 = 554,268.
*Ignoring chronological order, there are 12!/6! = 22!!!! = 665,280 possible combinations for a matchday in a 12-team league, such as the .
*In some countries, there are s involving 13 matches. The number of possible combinations is 313 = 1,594,323.
*In some countries, there are s involving 14 matches. The number of possible combinations is 314 = 4,782,969.
*Since there are 211 FIFA members, and at most one of the 11 OFC members may qualify for the FIFA World Cup, there are 200P3 + 3 × 11 × 200P2 = 9,193,800 possible combinations for the three highest ranked nations.
*For the of the , the eight seeded teams have to be drawn against the eight unseeded teams. The number of possible outcomes is 8! × 28 = 16!! = 10,321,920. In reality, the actual number is almost always smaller, since teams of the same association cannot be drawn against each other.
*Ignoring chronological order, there are 14!/7! = 26!!!! = 17,297,280 possible combinations for a matchday in a 14-team league, such as the .

*For the of the UEFA Cup, the eight group winners had to be drawn against a third-placed team of another group, and the eight runner-ups had to be drawn against one of the eight third-placed teams from the UEFA Champions League. The number of possible outcomes was !8 × 8! = 598,066,560. In reality, the actual number would be almost always smaller (and was always smaller), since teams of the same association could not be drawn against each other.
*Since there are 211 FIFA members, and at most one of the 11 OFC members may qualify for the FIFA World Cup, there are 200P4 + 4 × 11 × 200P3 = 1,899,176,400 possible combinations for the four highest ranked nations.
*Ignoring chronological order, there are 18!/9! = 34!!!! = 17,643,225,600 possible combinations for a matchday in an 18-team league, such as the German .
*Ignoring chronological order, there are 20!/10! = 38!!!! = 670,442,572,800 possible combinations for a matchday in a 20-team league, such as the English .
*Ignoring the exact ranking of teams eliminated before the semifinals, there are 614 × 24 = 615 × 4 = 1,880,739,938,304 possible final rankings for the FIFA World Cup after the draw of the group stage.

The number of possible outcomes is !12 + 4 × !13 + 6 × !14 + 4 × !15 + !16 = 9,823,096,307,544. In reality, the actual number is almost always smaller, since teams of the same association cannot be drawn against each other.
*For the round of 32 of the , the sixteen seeded teams have to be drawn against the sixteen unseeded teams. The number of possible outcomes is 16! = 20,922,789,888,000. In reality, the actual number is almost always smaller, since teams of the same association cannot be drawn against each other.
*Ignoring chronological order, there are 22!/11! = 42!!!! = 28,158,588,057,600 possible combinations for a matchday in a 22-team league, such as the Spanish .

*There are 32!/16! = 62!!!! = 32P16 = 12,576,278,705,767,096,320,000 possible ways to draw the round of 32 of a single-elimination tournament (e.g 16 out of 32 rounds).
*There are 32!/60 = 4,385,513,948,894,892,169,453,633,536,000,000 possible ways to distribute the flags of 32 nations on the 32 faces of a football.
