Morgado Identity
There are several results known as the Morgado identity. The first is
![F_nF_(n+1)F_(n+2)F_(n+4)F_(n+5)F_(n+6)+L_(n+3)^2=[F_(n+3)(2F_(n+2)F_(n+4)-F_(n+3)^2)]^2,](https://mathworld.wolfram.com/images/equations/MorgadoIdentity/NumberedEquation1.gif) |

where 
is a Fibonacci number and 
is a Lucas number (Morgado 1987, Dujella 1995).
A second Morgado identity is satisfied by generalized Fibonacci numbers
