Of course, there are situations where you could have more than 512
valid values. In that case, you can either recompile with larger
bit sets (typically a multiple of 128, to get good use of SIMD),
or you can split into smaller sub-jobs; find all valid ways of
extending the sequence by one element (trivial; we already did
that to make the bit sets), and then make one job for each.
