Completion of the FLT regular project
We are proud to announce that as of December 5th 2023, the FLT regular project has been completed. We have formally verified the classical proof of Fermat's last theorem for regular primes two years after the project started. The blueprint for the project can be found here and the formalization itself is available on GitHub here.
Statement
We used the following definition of regular primes in the project.
/--
A natural number `n` is regular if `n` is coprime to
the cardinality of the class group of the `n`-th cyclotomic field.
