https://en.wikipedia.org/wiki/CombinatoricsCombinatorics is an area of mathematics primarily concerned with counting, both as a means and an end in obtaining results, and certain properties of finite structures. It is closely related to many other areas of mathematics and has many applications ranging from logic to statistical physics and from

https://en.wikipedia.org/wiki/Category:CombinatoricsCombinatorics is a branch of mathematics that studies finite collections of objects that satisfy specified criteria, and is in particular concerned with "counting" the objects in those collections (enumerative combinatorics) and with deciding whether certain "optimal" objects exist (extremal combinatorics).One of the most prominent combinatorialists of recent times was Gian-Carlo …

https://hu.wikipedia.org/wiki/Kombinatorika- Permutáció
Ismétlés nélküli permutáció alatt néhány különböző dolognak a sorba rendezését értjük. Az "ismétlés nélküli" arra utal, hogy a sorba rendezendő elemek különbözőek, azaz nem ismétlődnek. Egy n elemű halmaz összes permutációinak a száma:P n = n ! = n ⋅ ( n − 1 ) ⋅ ( n − 2 ) ⋅ … ⋅ 2 ⋅ 1. {\… - Kombináció
Az ismétlés nélküli kombinációt alkalmazzuk akkor, ha adott egy véges halmaz, melynek n darabszámú elemeiből k elemszámú halmazokat (kombinatorika nevén osztályokat) akarunk mindenféle módon képezni (és minden elem csak egyszer fordul elő). Ezt úgy hívjuk, hogy n ele…
