Oh. Ok.
So instead I will prove that no simple graph exists whose degree partition is discrete:
Firstly, assume that it does exist. Now, sort the vertices according to their degree. Note that the nth vertex can have a maximum of (n-1) bonds to the others. However, this only leaves (n - 2) other possible degrees for the remaining (n - 1) vertices, so two of the remaining vertices must share the same degree.
Q. E. Fucking D.
