Repeated Word List

Repeated Word List (short RepWL) is a decider. It works by splitting the tape contents into blocks ("words") of a given length $l$. Consecutive blocks are marked by exponents. If there are more than some predefined natural number, called the repeat threshhold $T$, consecutive repetitions, the exponent is given as $T+$. Consecutive blocks with no $+$ in their exponent are called constant blocks.
