Wouldn't this be something like 2^(160 - 4)( custom char vanity) = 2^156, although these aren't compressed... Not sure how it would work in that case.. 2^(34 - 4)?

(2^(34-5)) / (2^(33-4)), my mistake. I still don't think this is correct though.

Essentially infinite for most purposes.

So there no end for Single address
e.g my name bitcoin will be infinite, no one can crack it or regenerate my same pattern  
1Sturtxxxxxxxxxx can be infinite
