 OFFSET 0,1 COMMENTS This sequence is related to the sequences A071110 (for 5 successive integers) and A060316 (for 6 successive integers) and others sequences to come... Asymptotically the sequence tends to 67 (the first n for which a(n)=67 is n=1042). LINKS Gilles A. Fleury, Table of n, a(n) for n = 0..1500 CROSSREFS Cf.
