      putStrLn "+r — afterwards are several unique digits not greater than 8 in the descending order — the first one is the length of the group of syllables to be considered as a period, the rest — positions of the maximums and minimums. Example: \"543\" means that the line is splitted into groups of 5 syllables starting from the beginning, then the positions of the most maximum (4 = 5 - 1) and the next (smaller) maximum (3 = 4 - 1). If there are no duplicated values then the lowest possible value here is 0, that corresponds to the lowest minimum. If there are duplicates then the lowest value here is the number of the groups of duplicates, e. g. in the sequence 1,6,3,3,4,4,5 that is one group there are two groups of duplicates — with 3 and 4 — and, therefore, the corresponding data after +r should be 7...2. The values less than the lowest minimum are neglected."
