Abstract

Building on work of Balakrishnan, Dogra, and of the first author, we provide some improvements to the explicit quadratic Chabauty method to compute rational points on genus 22 bielliptic curves over Q\mathbb{Q}, whose Jacobians have Mordell-Weil rank equal to 22. We complement this with a precision analysis to guarantee correct outputs. Together with the Mordell-Weil sieve, this bielliptic quadratic Chabauty method is then the main tool that we use to compute the rational points on the 411411 locally solvable curves from the LMFDB which satisfy the aforementioned conditions.
