A maximal nilpotent subgroup of a group that coincides with its normalizer. Introduced by R. Carter [1]. Any finite solvable group has a Carter subgroup, and all Carter subgroups of are conjugate (Carter's theorem).

Comments
An example of a non-solvable group having no Carter subgroup is , the alternating group of order 5.
Any Carter subgroup of a finite solvable group is a maximal nilpotent subgroup.
