 time grows faster than proportional to the linear system size -- and

+To see how a comparison of this kind could work, take a look at
+@cite KronbichlerWall2018 , and specifically Figure 5

+a number of polynomial degrees (as well as a number of different ways

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
