 \section{A Case Requring More Aggressive Simplifications}
 For example, when starting with the regular
-expression $(a^* \cdot a^*)^*$ and building a few successive derivatives (around 10)
+expression $(a^* \cdot a^*)^*$ and building just over
+a dozen successive derivatives 
 w.r.t.~the character $a$, one obtains a derivative regular expression
-with more than 9000 nodes (when viewed as a tree)
-even with simplification.

+even with simplification, which is not much better compared
+with the naive version without any simplifications:
