Determination of Boolean function of encoding is in-process given during work with the bytes of report, the algorithm of encoding is considered, possibility of equivalent presentation of Boolean function is rotined as transposition, the table of func-tions of encoding-decoding is resulted. The rule of receipt of reverse function is rotined.
