OEIS Sequences

a(n) = number of (s(0), s(1), ..., s(n)) such that every s(i) is an integer, s(0) = 0, |s(i) - s(i-1)| = 1 for i = 1,2; |s(i) - s(i-1)| <= 1 for i >= 3, s(n) = 3. Also a(n) = T(n,n-3), where T is the array defined in A024996. A26070

After the 51-digit 2¹⁶⁸, a(n) is the number setting a record for non-pandigital right segment length of 2^a(n). A217608

a(n) = ∑_k=0..2n-3 T(n,k) * T(n,k+3), with T given by A025177. A27260
