Conjunction of normality with any nontrivially satisfied group property not implies characteristic
Statement
In terms of groups
Suppose is a nontrivial group. Then, there exists a nontrivial group containing as a normal subgroup such that is not a characteristic subgroup of .
In terms of properties
Suppose is a group property satisfied by some nontrivial group. Then, the property of being a normal subgroup that satisfies as a group does not imply the property of being a characteristic subgroup.
