I would gladly disable gmp library for python but from previous experience this provokes a lot of nagging.

Thanks ! I was suprised it wasn't on OEIS yet. I'm glad that such autistic idea came to someone else too.

Looks like it's side effect from library blocker, which is written not by me so I can't manage that. Although importing concrete functions from math library seems to be working.

Because you use naive solution. You can try it on easier version, mentioned in the description. This one requires more complex solution.

Originally I set estimated rank as 6 kye. It's not my fault that this got to 4

Thanks for advise, I changed description.

[0] should be []

I think this issue raises when you divide polynomial by constant and as result one of the Bezout's coefficients should be zero. Although it is more logical to set zero initialized list in this situation than just empty list. I hope it will not ruin already submitted solutions.

resolved

for given polynomials a, b find polynomials x, y such that ax + by = d, where d = gcd(a, b)

I will update them later but firsly I should find the bug
