Permutation Group
A finite Group of substitutions of elements for each other. For instance, the order 4 permutation group 
would rearrange the elements 
in the order 
. A SubstitutionGroup of two elements is called a Transposition. Every Substitution Group with 
elements can bewritten as a product of transpositions. For example,
 |  |  | |
 | |  |
Conjugacy Classes of elements which are interchanged are called Cycles (in the above example, the Cycles are
).See also Cayley's Group Theorem, Cycle (Permutation), Group, Substitution Group, Transposition- Slothouber-Graatsma Puzzle
