Slanted edge.

<p>(A) 3D edge sideways. (B) 3D edge at an angle to display the face where it connects to the node. Nodes are not shown to simplify the visualization. (C-D) Sketch of one of the portions that make up the fiber. (C) Shows that for every short fiber there are two of the long ones. (D) Shows a short side, which has a length of √3 and the longer one is 2√3. (D) Shows the triangular cross section of the fiber, yielding a higher number of longer fibers compared to the short ones.
