im struggling to find a solution to the 4waymux16, can you offer some tips or something?  
I'm confused about the selector bits, i thought at first of doing it the same way you would do a multi-way and gate for example, piping hte output from one mux16 to the next mux16, so i drew 3 mux16's connecting outputs to inputs, but that way you would have 3 selector bits. and so it doesn't seem to be right.. the other way i thought was a mux16 for a and b, a mux 16 for c and d and their outputs going to a 3rd mux16. which is also evidently wrong...  im really struggling to wrap my head around this..
