W73 (nuclear Warhead)
The W73 was a planned nuclear warhead for the AGM-53 Condor air to surface missile and designed by Los Alamos Scientific Laboratory (now Los Alamos National Laboratory). The W73 warhead was cancelled in 1970 in favor of a purely conventional warhead for Condor. Condor was approved for production in 1975 with a expected production run of 250 missiles, but was cancelled in early 1976 due to high cost. The weapon was reportedly derived from the B61 nuclear bomb and had a diameter of . Condor was to weigh at launch and carry a warhead. It is unclear if the weight given is for the conventional or nuclear-armed version of the Condor.

Dodecadodecahedron
In geometry, the dodecadodecahedron is a nonconvex uniform polyhedron, indexed as U36. It is the Rectification (geometry), rectification of the great dodecahedron (and that of its dual, the small stellated dodecahedron). It was discovered independently by , and . The edges of this model form 10 central hexagons, and these, projected onto a sphere, become 10 great circles. These 10, along with the great circles from projections of two other polyhedra, form the 31 great circles of the spherical icosahedron used in construction of geodesic domes. Wythoff constructions It has four Wythoff constructions between four Schwarz triangle families: 2 , 5 5/2, 2 , 5 5/3, 2 , 5/2 5/4, 2 , 5/3 5/4, but represent identical results. Similarly it can be given four extended Schläfli symbols: r, r, r, and r or as Coxeter-Dynkin diagrams: , , , and . Net A shape with the same exterior appearance as the dodecadodecahedron can be constructed by folding up these nets: 12 pentagrams and 20 ...
