Euler added the rational number 777480/8288641. %C A192630 Stoll proved that an extension of Fermat's set to a rational quintuple with the same property is unique. - _Andrej Dujella_, May 12 2024 %C A192630 Numerators are A192629. %C A192630 See A030063 and A192629 for additional comments, references, and links. %H A192630 Michael Stoll, <a href="https://doi.org/10.4064/aa180416-4-10">Diagonal genus 5 curves, elliptic curves over Q(t), and rational diophantine quintuples</a>, Acta Arith. 190 (2019), 239-261. %e A192630 0/1, 1/1, 3/1, 8/1, 120/1, 777480/8288641. %e A192630 1 + 1*(777480/8288641) = (3011/2879)^2. %Y A192630 Cf.
