 OFFSET 1,1 COMMENTS This sequence is related to the sequences A071110 (for 5 successive integers) and A060316 (for 6 successive integers). What is the asymptotic value of this sequence? What is the first n for which a(n) equals the asymptotic value? LINKS Gilles A. Fleury, Table of n, a(n) for n = 1..51 CROSSREFS Cf. A071110, A060316, A071107, A060315, A141494, A142153.
