[math-fun] Knight's move sequences

Yesterday I added four sequences to OEIS with ID's A242511-4 , concerned with squares which have many alternative shortest knight paths from the origin. Several people have replied with suggestions, for which I am grateful. However having swallowed my sequences OEIS is currently refusing to admit to me even that they exist, let alone permit me to edit them; I'm afraid clarifications will have to wait until this situation improves.
