Group theoryBroader topic: Cosets organize a group into equal-sized pieces around a subgroup.
GroupBroader topic: Cosets partition a group and underpin the construction of quotient groups.
Finite groupRelated: Cosets partition finite groups and underpin Lagrange’s theorem.
Quotient groupBroader topic: Each element of the quotient group is a coset of the subgroup.
SubgroupRelated: Cosets partition a group according to a chosen subgroup.
Quotient ringRelated: Each quotient-ring element is a coset of the defining ideal.
Cayley graphRelated: Cosets can index vertices in related graphs built from group actions.
Conjugacy classRelated: Class sizes are indices of centralizers, hence counts of cosets.
Quotient spaceBroader topic: Each element of the quotient is one coset v + W.
