摘要
我们应用 Diophantine 分析法对球面上全等边四边形（即边组合 \(a^3b\)）的边对边平铺进行分类。与 Cheung、Luk 和 Yan 的完整分类方法并行，这里实现的方法更加系统化，并适用于其他相关的平铺问题。我们还提供了平铺的详细几何数据。
Rational Angles and Tilings of the Sphere by Congruent Quadrilaterals
We apply Diophantine analysis to classify edge-to-edge tilings of the sphere by congruent almost equilateral quadrilaterals (i.e., edge combination \(a^3b\)). Parallel to a complete classification by Cheung, Luk, and Yan, the method implemented here is more systematic and applicable to other related tiling problems. We also provide detailed geometric data for the tilings.
