小斜方截半立方体
Also known as small rhombicuboctahedron
The rhombicuboctahedron or small rhombicuboctahedron is a polyhedron with 26 faces, consisting of 8 equilateral triangles and 18 squares. It was named by Johannes Kepler in his 1618 Harmonices Mundi, being short for truncated cuboctahedral rhombus, with cuboctahedral rhombus being his name for a rhombic dodecahedron.

在幾何學中，小斜方截半立方體，又稱為菱方八面體，是一種有18個正方形和8個正三角形的阿基米德立體。小斜方截半立方體共有26個面、48條邊以及24個頂點，具有點可遞性質，因此既是均勻多面體也是半正多面體。
