• Continued fraction expansion of the constant (A114550) equal to Sum_{n>=0} 1/A112373(n) such that the partial quotients satisfy a(2n) = A112373(n) for n > 0 and a(2n+1) = A112373(n+1)/A112373(n) for n >= 0.at n=9A114551
• Odd-indexed bisection of A114551, which is the continued fraction expansion of Sum_{n>=0} 1/A112373(n); also, a(n) = A112373(n+1)/A112373(n) for n>=0.at n=4A114552
• Number of 0..2 arrays of length n with each element differing from at least one neighbor by something other than 1, starting with 0.at n=13A221536
• G.f. satisfies A(x) = 1 + x * (1 + x^3)^2 * A(x * (1 + x^3)).at n=17A360889
