I think this assertion part is obsolete, in the form of "assert(islychrel(n))" or "assert(~islychrel(n))" now will fail directly on the new cody system. my code run at my computer seems fine by the way.
It looks like there is an error in the test suite, because 3664 becomes 475574 after 5 iterations, although the test suite says that it's not a Lychrel number. (In addition, OEIS A023108, which lists all non-Lychrel numbers up to 3675, excludes 3664).
Currently, the test suite seems to be working fine.
ok! sorry for this, I missunderstood the problem... :-(
my solution is here:
So, I'M NOT LEADER IN THIS PROBLEM!
