Subgroups of all orders dividing the group order not implies supersolvable
This article gives the statement and possibly, proof, of a non-implication relation between two group properties. That is, it states that every group satisfying the first group property (i.e., group having subgroups of all orders dividing the group order) need not satisfy the second group property (i.e., supersolvable group)

Statement
Statement with symbols
It is possible to have a finite group with subgroups of all orders dividing the order of , with not a Finite supersolvable group (?).
Proof
Example of the symmetric group of degree four
Further information: symmetric group:S4, subgroup structure of symmetric group:S4
The symmetric group of degree four has subgroups of every order dividing its order. There are cyclic subgroups of order ; there is a dihedral Sylow subgroup of order ; there is a symmetric group on three elements of order , and there is an alternating group of order .
On the other hand, this group does not have any cyclic normal subgroups at all, hence it is not supersolvable.
