My code? I've been working with a group of developers from NASA to try and figure out wtf your $e var is doing
Basically my code, just enumerates all possible combinations (for loops), keeps a count of how many times i've 'seen' that combination ($t array), ensures that a 'file piece' is only used once per combination ($b array) and also make sure i don't create a combination by adding a 'file piece' to itself - that would be impossible ($i=$j stuff)
if every piece can be used for the same combination (count=ubound+1) - we're done.
