abelian group
group whose group operation is commutative
cyclic group
mathematical group that can be generated as the set of powers of a single element
dihedral group
group of symmetries of a regular polygon
finite group
mathematical group based upon a finite number of elements
simple group
group without normal subgroups other than the trivial group and itself
solvable group
group that can be constructed from abelian groups using extensions; a group whose derived series terminates in the trivial subgroup
free group
free object in the category of groups; a group admitting a presentation without any relations
algebraic group
group that is an algebraic variety
nilpotent group
group that has an upper central series terminating with G
free abelian group
commutative group whose elements are unique integer combinations of basis elements
divisible group
abelian group in which every element can, in some sense, be divided by positive integers
torsion group
group in which each element has finite order

Dedekind group
group such that every its subgroup is normal
hyperbolic group
Mathematical concept
Complete group
finitely generated group
group G that has some finite generating set S so that every element of G can be written as the product of finitely many elements of the finite set S and of inverses of such element
perfect group
group with trivial abelianization
non-abelian group
group where ab = ba does not always hold
triangle group
Group realized geometrically by reflections across the sides of a triangle
Hopfian group
group for which every surjective endomorphism is bijective
polycyclic group
in mathematics, a solvable group that satisfies the maximal condition on subgroups
residually finite group
type of mathematical group
locally finite group
type of group
prosolvable group
a topological group that is isomorphic to the inverse limit of an inverse system of solvable groups
word metric
way to measure distance between any two elements of group (in group theory)
almost simple group
a group that fits between a non-abelian simple group and its automorphism group
Nielsen–Schreier theorem
theorem that every subgroup of a free group is itself free
characteristically simple group
mathematical group that has no proper nontrivial characteristic subgroups
metabelian group
group G with abelian normal subgroup N and abelian quotient group G/N (equivalently: group with abelian commutator subgroup)
