Thinking about this further, I've confused myself again. What does it mean to
"find" a composition? With c. 450 billion of them you surely can't be writing
them out to a file or anything. If we conservatively estimate 50 bytes per
composition, that would still be be over 20 terabytes.
Come to think of it, is "billion" in this context 10^9? Or in the UK does
"billion" instead mean 10^12? In which case that would be over 20 petabytes!
