This one can be obtained by chopping off the 72 vertices of an ex, which correspond to 3 vertex-inscribed f-icoes. In fact 72 ikepy are to be cut off. But in contrast to sadi those ikepy would intersect here, resulting in bitdi cells instead, which also show up some f-sized edges. – Tridex likewise can be obtained from sadi by chopping off the 48 vertices of 2 further vertex-inscribed f-icoes, or from bidex by diminishing at those of 1 such. For more details cf. here.
