Abstract
The GRP transform, or the generalized radix permutation transform was proposed as a parametric generalization of the BWT of the block-sorting data compression algorithm. This paper develops its extension that can be applied with any combination of parameters. By using the technique developed for linear time/space implementation of the sort transform, we propose an efficient implementation for the inverse transformation of the GRP transform. It works for arbitrary parameter values, and can convert the transformed string to the original string in time linear in the string length.
