Extending A019565 to create a permutation of natural numbers.

Written by Michael Thomas De Vlieger, St. Louis, Missouri, 2023 0127.

Abstract.

We introduce a permutation of natural numbers based on A019565, which itself is a permutation of squarefree numbers. This permutation of natural numbers, generated from a permutation of squarefree numbers κ, has the interesting property of generating columns that list the strongly κ-regular numbers in order.
