Let S_n be the set of all positive integers except a(1), a(2), ..., a(n-1) and a(n). Let k_n be the number of members of S_n that are less than a(n). (k_n = A091068(n+1).) If k_n >= n, then a(n+1) is the (1+k_n-n)th member of S_n; if k_n < n then a(n+1) is the (k_n+n)th member of S_n. - David Wasserman, Feb 23 2006
