Abstract
In this paper we show that the set of plus- respectively minus-decomposable permutations of a regular class under the rank encoding form regular sublanguages. Plus- respectively minus-decomposable permutations are permutations allowing for a special kind of block-decomposition. The language theoretic results shown have different approaches, even though the properties of plus- and minus-decomposability of permutations are similar.
