Fibonorial
Mathematical series, portmanteau of "Fibonacci" and "factorial"
In mathematics, the Fibonorial n!F, also called the Fibonacci factorial, where n is a nonnegative integer, is defined as the product of the first n positive Fibonacci numbers, i.e. n ! F := ∏ i = 1 n F i , n ≥ 0 , {\displaystyle {n!}_{F}:=\prod _{i=1}^{n}F_{i},\quad n\geq 0,} where Fi is the ith Fibonacci number, and 0!F gives the empty product (defined as the multiplicative identity, i.e. 1).

From Wikipedia
In mathematics, the Fibonorial n!F, also called the Fibonacci factorial, where n is a nonnegative integer, is defined as the product of the first n positive Fibonacci numbers, i.e. n ! F := ∏ i = 1 n F i , n ≥ 0 , {\displaystyle {n!}_{F}:=\prod _{i=1}^{n}F_{i},\quad n\geq 0,} where Fi is the ith Fibonacci number, and 0!F gives the empty product (defined as the multiplicative identity, i.e. 1). The Fibonorial n!F is defined analogously to the factorial n!. The Fibonorial numbers are used in the definition of Fibonomial coefficients (or Fibonacci-binomial coefficients) similarly as the factorial numbers are used in the definition of binomial coefficients.
