Both, the triangles and the hexagons pairwise fall into coincident face planes. So either both can be considered separately (type A); or triangles only are considered as (rotated) 2-triangle-compounds (type B); or hexagons only are considered as (rotated) 2-hexagon-compounds (type C); or both are considered as non-regular compounds.
