I would like to create a fixture logarithm for a list of 24 teams. I would like to have each team play the other 23 teams home and away. For example:

4 Teams

1 v 2
3 v 4
1 v 3
2 v 4

etc...

Any ideas on how i could go about starting this???

PHP Code:

<?
    $teams = array(1, 2, 3, 4);

    foreach ($teams as $homer) {
        foreach ($teams as $guest) {
            if ($homer == $guest)
                continue;

            echo "$homer v $guest\n";
        }
    }
?>

And then learn what is logarithm and how does it differ from algorithm
