       # MATH introduce numbers (in unary notation)
       # Here we count up, go through some primes, etc.
       # There is some syntax around the numbers, but that doesn't
       # need to be understood at this point.
       # Any 'words' written here are converted to arbitrary integers
       # in the actual message. Any word ending in -in-unary will be given
       # in unary rather than the binary code used in the main body
       # of the message.
