Normality is not transitive
Did you know?
WebIn group theory it is a familiar observation that normality of subgroups is not in general a transitive relation, i.e., H K G need not imply that H G. The smallest group exhibiting this phenomenon is Dih(8), the dihedral group of order 8. WebThe discrete-event system (DES) to be controlled (i.e. the plant) is modeled by an automaton where Z is the alphabet of event labels, Q is the set of states, 6: Z X Q + Q is the transition function (a partial function), q0 is the initial state, and Q, c Q is the set of marked states. The behavior of the DES is described by the language ...

WebA normal subgroup of a normal subgroup of a group need not be normal in the group. That is, normality is not a transitive relation. The smallest group exhibiting this phenomenon is the dihedral group of order 8. [15] However, a characteristic subgroup of a normal subgroup is normal.

We say that G is a T 0 -group, if its Frattini quotient group G/\Phi (G) is a T -group, where by a T -group we mean a group in which every subnormal subgroup is normal. We determine the structure of a non T 0 -group G all of whose proper subgroups are T 0 -groups.
