I believe an inverter (not gate) is required...

You can route a wire to both inputs of a NAND or NOR gate to create a NOT.

Where do you think the N in NOR and NAND come from?

That makes it sound like you could also do a NOT with XNOR, which is only the case if you can use a constant 0. But that would similarly also be the case for a XOR, but with the requirement of a 1.

That’s cool, but I meant to imply it is kind of backwards to make a NOT gate with a component that itself is fundamentally built out of a NOT gate.
