You've just used 32 bits to describe data with 17 bits of entropy.
That's not a crime, nor particularly bad as an encoding.

But what I meant would take a little thought would be designing a
generic encoding (for all N and M) that encoded using no more bits than
the inherent entropy of a ranked preference contest. Of course, I'll
round up to the nearest bit rather than use fractional bits. It won't
take any act of genius to accomplish this, just, well, a little
