Abstract: In finite groups that are not abelian, at most 3/4 of
pairs of elements will commute. A natural question is
whether this gap extends to measures of "Hamiltonianess".
In fact, this paper shows that for any rational number r
between 0 and 1, there exist groups where the probability
that a subgroup chosen uniformly at random from the set of
subgroups is normal is exactly r. The proof technique was
suggested through computer experimentation.
