• Centre of a group [r]: The subgroup of a group consisting of all elements which commute with every element of the group. [e]
• Character (group theory) [r]: A homomorphism from a group to the unit circle; more generally, the trace of a group representation. [e]
• Characteristic subgroup [r]: A subgroup which is mapped to itself by any automorphism of the whole group. [e]

• Euler's theorem (rotation) [r]: In three-dimensional space, any rotation of a rigid body is around an axis, the rotation axis. [e]
• Exact sequence [r]: A sequence of algebraic objects and morphisms which is used to describe or analyse algebraic structure. [e]
