Properties
- The kernel of an isomorphism from (G, *) to (H, ), is always {eG} where eG is the identity of the group (G, *)
- If (G, *) is isomorphic to (H,), and if G is abelian then so is H.
- If (G, *) is a group that is isomorphic to (H, ), then if a belongs to G and has order n, then so does f(a).
- If (G, *) is a locally finite group that is isomorphic to (H, ), then (H, ) is also locally finite.
- The previous examples illustrate that 'group properties' are always preserved by isomorphisms.

“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (18031882)
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (16321704)
