Triangles and squares each pairwise fall into coincident face planes. So either they both can be considered separately (type A); or triangles are considered as (regular) 2-triangle-compounds while squares are kept separately (type B); or triangles are kept separately while squares are considered as (rotated) 2-square-compounds (type C); or both are considered as compounds.
