Four parameter values of period doubling are

\begin{displaymath}\lambda_1&=10.5710\cr\end{displaymath}


\begin{displaymath}\lambda_2&=10.1465\cr\end{displaymath}


\begin{displaymath}\lambda_3&=10.0912\cr\end{displaymath}


\begin{displaymath}\lambda_4&=10.0808.\cr\end{displaymath}



The expected accumulation point is $\lambda_\infty =10.078$.
