Appears in sequences

• a(1) = 1; a(n+1) is the smallest number > a(n) which differs from it at every digit.at n=41A068860
• The sequence alternates even and odd integers but also even and odd digits; it is monotonically increasing and a(n) is always the smallest integer fitting the pattern.at n=22A137667
• a(n) = 81*n^2 - 90*n + 26.at n=28A154295
• Triangle read by rows: T(n,k) = 1 + (A022166(n,k) - binomial(n,k))^2.at n=37A174918
• Triangle read by rows: T(n,k) = 1 + (A022166(n,k) - binomial(n,k))^2.at n=43A174918
