%%visits: 2 There are specific properties of a klien 4 group.
kliens_four-grou := $V_4 := A group with the
rules | | e | a | b | c |
|—–|—–|—–|—–|—–| | e | e | a | b | c | | a | a | e | c
| b | | b | b | c | e | a | | c | c | b | a | e |
There are no non-abelian groups of order less than or equal to 5.
V4 is the smallest non-cyclic group
V4 is such that all elements different from e V4 has the subgroups, ⟨a⟩, ⟨b⟩, ⟨c⟩, e, V4 and ⟨a⟩ ≡ ⟨b⟩ = ℤ4
