It's defined right above (LGnumBITS is 24 on 32-bit machine), and there a
huge comment there to explain the parameters defining the codeword
structure.

You could make LGnumBITS slightly larger in your binary (at most 26 on 32
bit machine). But why not break the vector into smaller parts ? Btw, have a
look at the FAQ:
