Hi,

Looking at the documentation at
http://maxima.sourceforge.net/docs/manual/en/maxima_5.html#IDX113 of
make_random_state, it suggest that the state of the random number
generator is comprised of 627 32-bit words, however in the MT19937
paper and other references to the random number generator there are
624 32-bit words in the generator. Is 627 a typo, or is there some
significance to these extra 3 x 32-bits?

Thanks!
