Rombohedraalisia
Rombohedraalisia is a hypothetical geometric shape that combines characteristics of a rhombohedron and a sphere. Imagine a shape that is generally spherical in its outward curvature but possesses flattened faces reminiscent of a rhombohedron. These faces would not be perfectly flat but would exhibit a slight concavity or convexity, creating a transition between the spherical and polyhedral forms. The edges where these "faces" meet would be rounded, further blending the distinct geometric features.
The concept of a rombohedraalisia is not a formally defined mathematical object in Euclidean geometry. It exists
