 Sep1 awarded Popular Question Feb25 comment Students at Table Permutation That shows me the number of possibilities - but what would be the easiest way to generate them? Feb25 comment Students at Table Permutation The order or how the students are grouped at each table doesn't matter, no. Just as long as the students never encounter each other again after encountering each other once.

However, if the set were to fulfill the requirements of the Cantor set, would that be $f_3(x)$? Jan8 comment Iterated Function System Definition I do realize that the functions could be completely arbitrary, but I was interested in distinguishing how IFSs are used with fractals. Jan8 accepted Iterated Function System Definition Jan8 comment Iterated Function System Definition Oh, I see. If it were to be a fractal, however, would that be the case? Jan8 comment Iterated Function System Definition You would have to provide a starting function though, correct? In other words, it would always be $f_1(x)$. Jan8 comment Iterated Function System Definition The only implicit assumption is that $f(x)$ is somehow defined and that, as you said, each one maps $X$ to itself? Jan8 comment Iterated Function System Definition Would the third function be: $f_3(x) = \frac{x}{3} + \left( \frac{2}{3} + \frac{\frac{x}{3} + \frac{2}{3}}{3}\right)$? Jan8 asked Iterated Function System Definition Feb27 comment Leibniz Rule Check: $h(x)=\int_{0}^{2x - 1} f(t) dt$ That makes sense - so at $x = 2.5$ there is a relative maximum.

Makes sense, thanks.
