It turns out that Apache is the first real drag (I ignore IEs laughable URL
length limit of 2083):

If we have the n-th element of stage m, then bit x of n tells if the x-th 
element from stage m - 1 is element of it.

 http://www.brunni.de/sets/v6.cgi

Now having the element number of stage 6 in the URL needs up to 65536 
characters with base 2, 19728 with base 10 and 10922 with base 64 - I'll have 
to recompile Apache.

The element number for stage 7 would need 2^65536 bits and I see no other
way to enumerate it.
