 OFFSET 0,3 COMMENTS This is self-inverse permutation (involution) of the nonnegative integers. LINKS Table of n, a(n) for n=0..69. Index entries for signature-permutations of Catalan automorphisms CROSSREFS a(n) = A125976(A057164(n)) = A057164(A125976(n)). Differs from A071663 for the first time at n=43, where a(n)=34, while A071663(n)=48. Sequence in context: A085178 A146942 A126313 * A071663 A071664 A130921 Adjacent sequences: A125976 A125977 A125978 * A125980 A125981 A125982 KEYWORD nonn AUTHOR Antti Karttunen, Jan 02 2007 STATUS approved
