• Square spiral sequence: numbers are placed in a square spiral, a(1)=1, a(n) is found as the sum of the row (in the previous direction) a(n-1) is in.at n=32A062410
• Convolution of Fibonacci F(n+1), n >= 0, with F(n+3), n >= 0.at n=19A067331
• a(n) = a(n-1) + a(n-2) + F(n), with a(0) = 0, a(1) = 1, a(2) = a(1) + a(0), a(3) = a(2) + a(1), a(4) = a(3) + a(2) + 2.at n=22A166106
