Center of binary octahedral group

From Groupprops
Jump to: navigation, search
This article is about a particular subgroup in a group, up to equivalence of subgroups (i.e., an isomorphism of groups that induces the corresponding isomorphism of subgroups). The subgroup is (up to isomorphism) cyclic group:Z2 and the group is (up to isomorphism) binary octahedral group (see subgroup structure of binary octahedral group).
The subgroup is a normal subgroup and the quotient group is isomorphic to symmetric group:S4.

third derived subgroup derived subgroup of derived subgroup of derived subgroup derived subgroup is isomorphic to SL(2,3), second derived subgroup is isomorphic to quaternion group
socle join of all minimal normal subgroups It is the unique minimal normal subgroup. The group is a monolithic group.
