You can also see how five copies of the pentadentrite fit together by successively adding copies using the buttons below, or by viewing the Lsystem animation farther down.
The scaling factor is still r = 0.381966. This leads to the following IFS [Details]:
\({f_1}({\bf{x}}) = \left[ {\begin{array}{*{20}{c}}
{0.341} & {  0.071} \\
{0.071} & {0.341} \\
\end{array}} \right]{\bf{x}}\)
