Antti Karttunen, Table of n, a(n) for n = 0..12917

Other identities. For all n >= 0:

a(n) = A155043(A263265(n)).

a(A263260(n)) = n+1. [The sequence is one more than the least monotonic left inverse of A263260.]

(Scheme, with Antti Karttunen's IntSeq-library)

(define A263270 (COMPOSE 1+ (LEFTINV-LEASTMONO 0 0 A263260)))
