在几何学中, 无限阶无限边形镶嵌是一种双曲面的正镶嵌。其施莱夫利符号为{∞,∞}, 代表其有着无限个无限边形围绕于其所有的无穷远点。
该镶嵌的对偶镶嵌代表*∞∞对称性的基本域。
该镶嵌可以在[(∞,∞,∞)]对称性中以三种不同的位置进行交错涂色。
基本域 | 0 | 1 | 2 |
---|---|---|---|
![]() 对称性 [(∞,∞,∞)] ![]() ![]() ![]() ![]() |
![]() t0{(∞,∞,∞)} ![]() ![]() ![]() ![]() |
![]() t1{(∞,∞,∞)} ![]() ![]() ![]() ![]() |
![]() t2{(∞,∞,∞)} ![]() ![]() ![]() ![]() |
该镶嵌及其对偶镶嵌的复合图形能以正交的红线及蓝线区分。而其组合定义了*2∞2∞基本域的线。

即使无限阶无限边形已经达到双曲镶嵌的极限了,但仍可使用虚数来表示更高的边数以及阶数。
