• a(n) = Sum_{k=0..n} A026615(n, k).at n=16A026622
• a(3) = 1, otherwise a(n) = n*2^(n-3) - 2^(n-2) - 2.at n=13A058966
• a(0)=1, a(1)=2, a(2)=1; for n>2, a(n) = 7*2^(n-3)-2.at n=17A174317
• a(n) = 7*2^n - 2.at n=14A176448
• a(0)=0, a(1)=1, for n>1, a(n) = n<*>n, where k<*>m = k<+>k<+>...<+>k is the m-1-fold iteration of the operation <+> defined in A206853.at n=14A206960
• Let h(m) denote the sequence whose n-th term is Sum_{k=0..n} (k+1)^m*T(n,k)^2, where T(n,k) is the Catalan triangle A039598. This is h(4).at n=4A228330
• a(n) - 2*a(n-1) = period 2: repeat [3, 0] for n > 0, a(0)=5, a(1)=13.at n=14A322417
