SuFac

Explicit plots of SuFac and that of factorial from [1]

SuFac, or super factorial, is superfunction of Factorial constructed with regular iteration at the fixed point $$L\!=\!2$$ with additional condition $$\mathrm{suFac}(0)\!=\!3$$.

Explicit plot $$y\!=\!\mathrm{SuFac}(x)$$ is shown in figure at right with blue curve in comparison with graphic of factorial, $$y\!=\!\mathrm{Factorial}(x)$$, shown with red line.

The numerical implementation in C++ of SuFac is loaded as sufac.cin.
