Presentation of a group
In
mathematics, one method of defining a
group is by a presentation. One specifies a set S of
generators so that every element of the group can be written as a product of some of these generators, and a set R of relations among those generators. We then say G has presentation Informally, G has the above presentation if it is the "freest group" generated by S subject only to the relations R. Formally, the group G is said to have the above presentation if it is
isomorphic to the
quotient of a
free group on S by the
normal subgroup generated by the relations R.
