SuperFactorial of real argument (Blue curve) in comparison with Factorial (Red curve).

Factorial is holomorphic solution of equations

$\mathrm{Factorial}(z\!+\!1)=(z\!+\!1)\, \mathrm{Factorial}(z)~$, $~\mathrm{Factorial}(0)\!=\!1$

SuperFactorial$(z)=\mathrm{Factorial}^z(3)$ is holomorphic solution of equations

$\mathrm{SuperFactorial}(z\!+\!1)=\mathrm{Factorial}\Big(\mathrm{SuperFactorial}(z)\Big)~$ , $~\mathrm{SuperFactorial}(0)\!=\!3$
