Yes, it's simple. Some things are, including me. The point I was trying to make is simple too. So many things are needlessly complicated by "what ifs?".

Count in binary, 0000...0000 (64 0f them) to binary 1111...1111 (64 0f them). Excluding rotations.

You want it in base ten? How human of you. I'm sorry, Dave. I'm afraid I can't do that. This mission is too important for me to allow you to jeopardize it.

But if you tell me how many are excluded by rotations that adhere to the Chess right hand white rule, I will open the pod bay doors.

It's easier than it seems.
