论文摘要
2016年，Izadi和Nabardi（B）显示（4-2-4）具有无限的整数解决方案。他们使用了特定的一致数椭圆曲线。 2020年，Ajai Choudhry，Iliya Bluskov和Alexander James（A）表明，方程（4-2-4）具有无限的许多参数解决方案。他们给出了N = 17,257,626,641,706,1921的数字解决方案。
In 2016 Izadi and Nabardi (b) showed (4-2-4) has infinitely many integer solutions. They used a specific congruent number elliptic curve.In 2019 Janfada and Nabardi,item C, showed that a necessary condition for n to have an integral solution for the above equation and gave a parametric solution.They gave the numeric solutions for n=41,136,313,1028,1201,3281. In 2020 Ajai Choudhry , Iliya Bluskov and Alexander James (a), showed that equation (4-2-4) has infinitely many parametric solutions. They gave the numeric solutions for n=17,257,626,641,706,1921.
