Question about kmaps and grouping

  1. Oct 6, 2011 #1
    1. The problem statement, all variables and given/known data
    I got a question about grouping of 1 in kmap,
    ex in 16 cell

    1100
    1100
    1110
    1010
    so i box the top left 4 then i box the two on the bottom right. now this part i dont get, they box 4 other ones overlapping the top box. why dont they just box the two by them self, also can you box a row of 3?, never seen it but dont know why. Does it have to go by 2 or something? Also the bottom left one why do they box that whole column, why not just box it the on on top?
    thanks
    also in a 3 variable k map, i never saw them box the whole row, they just box two in separate boxes why?

    also in
    0001
    0111
    0110
    0110
    they don't do the overlaping 4 cell boxes they just box the two on top and they show the static hazard it makes, so confusing lol


    2. Relevant equations



    3. The attempt at a solution
