@mindaugl Sorry, but 6 minutes is too long to accept such solution

386.85s call     scripts/validate_solutions.py::test_project_euler[problem_127/sol1.py]

The authors of the project mention the "one-minute rule" - https://projecteuler.net/about (now the longest accepted solution takes 10 seconds)

I've written my program but should it take days to get to the answer?
Absolutely not! Each problem has been designed according to a "one-minute rule", which means that although it may take several hours to design a successful algorithm with more difficult problems, an efficient implementation will allow a solution to be obtained on a modestly powered computer in less than one minute.

Fair enough, was thinking this would be initial solution, as multiple solutions are allowed, on which to improve.
