Rico can be obtained as hull of kitapna, which is the compound of 4 icoes. Spidrico is obtained therefrom by chopping off 24 of its vertex pyramids in a swirl-symmetric distribution, that is, it is the hull of just 3 of those icoes. All cubes thereby get reduced to qo3oq&#x, any co gets chirally tridiminished at every alternate vertex of its medial hexagon. Additionally the former vertex figures (x q3o) come in. (Thus it is an isogonal polychoron only.)
