I have something as below featuring XOR, AND, OR, XNOR, NAND and NOR gates. I have to get the bottom 3 outputs set to 1. As you can see, I've managed to do it as below but was wondering out of the 720 possible combinations, how many are there actually? Am I missing some logic myself or is there an online resource to help?
For the benefit of this, the inputs remain the same. Only the position of the gates can change.
