For each $n=4,5,6,7,8$
\begin{itemize}
\item Generation of Balanced Gray Codes $\leadsto$ 
  functions $f$ to iterate
\item Selection of the function $f*$ minimizing the mixing time $b$ 
\item Reproduced in the paper
\item Evaluation through NIST and DieHARD
\item $\leadsto$  all the generators pass the NIST and the DieHARD 
batteries of tests
\end{itemize}
