| Abstract: | |
|
Let π be an even permutation on n letters which has
a root, that is, there exists an even permutation ξ such that
π = ξ2. In this article the number of this kind of π is
found by using generating function techniques. This is the analogue
of a result for the number of all permutations with roots.
