Let's say I want to find derivative cycles, that is, a group of functions $\langle f_0, f_1, \ldots, f_{n-1} \rangle$ where ${f_0}^{(p)}(x)={f_{p\,\%\,n}}(x)$ where $\%$ is the modulo operator. For $n = 1$, we have the exponential function, $f_0 = ae^{x+k}$ for arbitrary $a$ and $k$. For $n = 2...

Do you lose the +2 edit rep if the edited post is subsequently deleted? It seems a little unfair if this is true, but reputation can evaporate in this way in similar circumstances.
