OEIS Sequences

Row sums of a characteristic triangle for the Fibonacci numbers. A110034

a(n) = F(n+1)² + F(n+1)*F(n) - F(n)², where F = A000045. A236428

a(n) = a(n-1) + a(n-3) + a(n-4), with a(0)=a(1)=a(2)=a(3)=1. A126116

Numbers w such that (F(2·n-1)², -F(2·n)², w) are primitive solutions of the Diophantine equation 2·x³ + 2·y³ + z³ = 1, where F(n) is the n-th Fibonacci number (A000045). A337929

a(n) = 288·n² - 168·n - 119. A118059

a(n) = a(n-1) + a(n-3) + a(n-4), where a(0) = 2, a(1) = 1, a(2) = 0, a(3) = 1. A295683

a(n) = F(n)*F(n+1) mod L(n+2) where F=A000045 is the Fibonacci numbers and L = A000032 is the Lucas numbers. A348592

a(n) = ( a(n-1) * a(n-3) + a(n-2) ) / a(n-4), a(1) = a(2) = 1, a(3) = -1, a(4) = -4. A206282
