2413-balloon permutations and the growth of the Möbius function

Autor: David William Marchant

We show that the growth of the principal Möbius function on the permutation poset is at least exponential. This improves on previous work, which has shown that the growth is at least polynomial.\ud \ud We define a method of constructing a permutatio
