Prog

(Scheme, requiring also defineperm1-macro from Antti Karttunen's IntSeq-library)
;; When A246165 is defined with defineperm1-macro, it will automatically cache also the inverse values, which are then available with negative arguments. Values of A246165 have to be computed first, for up to some value, before this can be used:
(define (A246166 n) (A246165 (- n)))
