COMMENTS

Theorem 9.7 from the Vatter reference: "There are only countably many growth rates of permutation classes below X but uncountably many growth rates in every open neighborhood of it. Moreover, every growth rate of permutation classes below X is achieved by a sum closed permutation class." (where X is the constant we are looking at)
