\end{equation}  This thas the odd implication that the $2^{nd}$ digit of $2^n$ is the sum of the last two digits of $2^{n+4}$...  But this can be rearranged to say \begin{equation}  D_1(n)=D_1(n-4)-D_0(n+1 \; mod 4) \; mod^* \; 10  \end{equation}  where $mod^*\;x$ as a construct insists that $-y \; mod^* \; x, \;\;y>0$ is $10-y$.
