Who solved fermats last theorem and how long did it take to solve

Fermat's Last Theorem was solved by Andrew Wiles. It was only solved 358 years after it was first created.

It depends on what type of third separates the three notes.for example: if you have two mayor thirds is an "aumented chord"if you have two minor thirds is an "diminued chord"if you have one mayor first and then one minor is a "mayor chord"and inverted is a "minor chord"
