If we use ASCII 7-bit char codes, 'w' is 0111 0111, and '7' is 0011 0111. 7 characters of 7 bits each gives a grand total of 49 flippable positions.

- detaro 6y agoand not all of the flip results are valid in domains, reducing the set. E.g. if 0111 0111 gets flipped to 0111 1111, that's not a valid character.
