Name external blend of 20 sidtid-0-3-3-3 edge facetings

Vertex figure [(3,5)3]/2, [32,52], [510]

blend-component:
sidtid-0-3-3-3  

It should be noted here, that the squares of the components (sidtid-0-3-3-3) are situated fully within the mirror planes underneath the edges of ike. Accordingly this (centrally hollow) external blend from 20 such self-intersecting polyhedra can be constructed, blending out all their squares (as if one each would be stuck onto each tip of an pseudo f3-gissid).
