Join of two finite subnormal subgroups is subnormal


This result was proved by Wielandt in Eine Verallgemeinerung der invarianten Untergruppen. Math. Z.45, 209–244 (1939).


Suppose H and K are two Finite subnormal subgroup (?)s of a group G. Then, the join of H and K is also a Subnormal subgroup (?) of G.
