Name sirdatady+1440{5/2}
Circumradius sqrt[3+sqrt(5)] = 2.288246
General of army hi
Colonel of regiment sidtaxhi
Confer sirdatady  

As abstract polytope sirdatady+1440{5/2} is isomorphic to gardatady+1440{5}, thereby interchanging pentagrams and pentagons, resp. replacing sidtid by gidtid and id by gid.

In this Grünbaumian polychoron it happens that the sidtid and the ditdid become co-realmic. Therefore any such pair looks like their blend, the gidtid, in addition to those pairs of coincident pentagrams, which while blending would be reduced. Accordingly, for sirdatady+1440{5/2}, edges and pentagrams come in coincident pairs too.
