Mathematics from the Polytechnic Museum solved the algorithm for the transformation of the sons of Yuri Chaika into LSDU3 and YFYAU9

Employees of the mathematics laboratory of the Polytechnic Museum revealed an algorithm, on the basis of which the names of the sons of the Russian Prosecutor General Artem and Igor Chakk turned into codes from letters and numbers in the official documents of Rosreestr, Snob writes with reference to the description of the algorithm received by the editor.

According to the algorithm, the name, patronymic and surname of a person are recorded together without gaps (for example, "Artemyuryevichchaika"). Then the sequence of letters is divided into blocks, in each of which the characters are included in four, starting from the first, second, third, fourth and fifth. So, in the example of Artyom Seagull, the blocks "Ayuik", "RRCHA", "TCH", "HEA" and "MVY" are obtained.

After that, each symbol from this sequence is replaced by the corresponding numerical code, which corresponds to the number of the letter in the alphabet, to which the number was added nine (a - 10, b - 11, etc.). Moreover, if in a combination that needs to be encrypted, there are numbers, they do not change.

By replacing the letters in previously compiled blocks with numbers, mathematicians calculated a certain set of coefficients for each block. So, for the first day of the first block, the coefficient was 38, for the second - 1, for the third - 4, for the fourth - again 4, etc. Then each figure from the block was multiplied by the coefficient assigned to it, and the works were formed among themselves. Thus, the first of five blocks in the example of Artem Seagull turned into 581.

The creators of the algorithm were divided into the number 43, which is the amount of the number of Arabic numbers (10) and letters in the Russian alphabet (33). The result of the division amounted to 13 with the remainder 22. This remainder is the code of the first letter or number in the encrypted name, that is, to find out which letter corresponds to 22, it is necessary to subtract from this number 9, having received 13. Under the 13th number in the alphabet, the letter "L", which will be the first letter of the code. The balance is less or equal 9 does not require additional operations and is recorded in the final combination in the form of a digit.

By applying this algorithm, you can completely get a combination of LSDU3, with which the name of Artyom Chaika in the documents of Rosreestr was replaced. The name of his brother, Igor Chaika, after applying the algorithm, turned into a yfyau9, and, for example, the encrypted name of Vladimir Putin has the form of a Chesh2z1.

At the same time, mathematicians note that the algorithm they found is not the only possible. “In fact, there are so many possible algorithms that even the head of the Polytechnic mathematics laboratory did not undertake to determine their number,” Ivan Bogantsev, Deputy General Director of the Polytechnic Museum, wrote on hisFacebook page.

To simplify the work with the algorithm and give users the opportunity to check it on other names, the museum representatives wrote a small program for Windows, which is currently available for download. You can also check the algorithm on the Medusa website.

Recall that the replacement of the names of the sons of the Prosecutor General in the documents of Rorestra about their property became known in early June. Representatives of the Corruption Fund found the substitution, and Alexei Navalny, who heads it, promised to sue Rosreestr.

The sons of the prosecutor General of Chaika were in the spotlight of the media and bloggers after the FBK at the end of last year released the sensational film about their business empire, foreign real estate and connections with the gang of the Tsapkov.
