RE: [PHP] math help

Anyone is free to correct me if I'm wrong... If you have 1,2,3,4,5 then you take the total which is 5, and take the factorial of it. 5! = 5 * 4 * 3 * 2 * 1 = 120 possibilities.

Can someone give me an idea of how to calculate total possibilities? For instance, given 1,2,3,4,5, how do I determine how many possible ways it will be to order them? 2,1,4,5,3, 3,2,4,5,1, etc. Thanks, Hans Anderson ~ me@hansanderson.com PO Box 426, Missoula, MT 59806 | PHP, Search Engines, SQL (800)397-9116 / (406)549-6524 | Databases, Flash Multimedia, http://www.hansanderson.com | Killer Audio Production, http://www.goofiness.com | Minty Fresh Breath. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
