Hello CASINO developers.
I wonder why the CASINO uses a spherical representation for the gaussian basic functions, while the сartesian representation requires a smaller number of computations to find both the values, derivatives and Laplacian etc.
There is no difference only for S and P the orbitals.
A spherical representation would be logical if the random walk of electrons was specified in spherical coordinates around single center, but this is not so.
Сould you tell me the reason for using the spherical representation, thank you in advance, Vladimir.

ChatGPT tackles every task with glee,
But turns it all to garbage, can't you see?
And when it handles garbage from the start,
At least it wastes less effort on its part.
