### On Serre's Equation X^4+Y^4=17 Z^4, by Samir Siksek

The manuscript 'On Serre's Equation X^4+Y^4=17Z^4' which I have circulated
in the past contains a computational error which renders the proof of the
main result invalid. I would like to retract all claims that I have solved
Serre's equation. I would also like thank G. Grigorov for discovering the
mistake.
