22. Each symbol in the Braille code is represented by a rectangular arrangement of six dots, each of which may be raised or flat against a smooth background. For instance, when the word Braille is spelled out, it looks like this: Given that at least one of the six dots must be raised, how many symbols can be represented in the Braille code?
