There are ways to overcome such limitations and render fractals with 
greater recursion depth. The most effective (in my experience) is to 
generate a mesh (either externally or in POV-SDL) of the fractal at a 
convenient depth, and then use that mesh as the low level building block 
in the bigger fractal. The reduction in memory usage can be quite 
dramatic. The important thing is to keep the total number of objects 
within reasonable bounds. 48^4 cubes is a little much for POV-Ray to 
handle; 48^2 or 48^3 mesh instances might work better. Unfortunately, 
POV-Ray doesn't handle huge meshes very well, but you might be able to 
reach level 5 (or more) that way.
