Appears in sequences

• Somos-4 sequence: a(0)=a(1)=a(2)=a(3)=1; for n >= 4, a(n) = (a(n-1) * a(n-3) + a(n-2)^2) / a(n-4).at n=12A006720
• Elliptic divisibility sequence associated with elliptic curve "37a1": y^2 + y = x^3 - x and multiples of the point (0,0).at n=21A006769
• A001333(n), n >= 1, convolved twice with itself.at n=8A054460
• a(n) = floor((1 + 1/Pi)^n).at n=40A179492
• A (25,-29) Somos-4 sequence.at n=5A352625
• Triangle read by rows: T(n,k) is the numerator of the n-th term of the Somos-k sequence, 4 <= k <= n.at n=36A354486
