This implies that this basis can be obtained by specifying one of these orbitals and obtain the others by rotating the first one. A possible realization is to align these orbitals along the slant edges of a pyramid with a regular polygon of order $2l+1$ as base [1,2]. Hence, the name "​Pyramidal Harmonics"​. Below we show these for $l=0...3$, but this can be done for every $l$. The first row depicts the view from the side, the second row depicts the view from the top along the z-axis. + From the [[physics_chemistry:​orbitals:​z|Tesseral Harmonics]] and for a given angular momentum ​$l$ one can construct an orbital basis where the basis orbitals have the same shape, but differ in orientation.
