Why, hello there. I'm doing Karnaugh maps. I'm using them to device gates to express the numbers 0, 1, 2, 3, 4 in a seven segmented digital display. Our teacher has provided us with predrawn Karnaugh maps, where we simply fill in the 1's and 0's. However, he's decided to invert the diagram, so that the first line reads: 0, 4, 12, 8, and the first column reads: 0, 1, 3, 2. I'm used to it being the other way around. And he specifically writes that "we'll be using a different order than what were used to in lectures". Is there any reason for this at all, or is it just to throw us off a bit? I can't figure out if there's any actual advantage to it.
