Tensegrity 2v{1,1} Double-Layer - Cold by TaffGoch Tensegrity 2v{1,1} Double-Layer - Cold by TaffGoch
Tensegrity sphere • Polyhedral basis: Icosahedron • Geodesic tessellation: Class-II • Frequency: 2v{1,1} • Composed of 60 interconnected "tripod" tensegrity-prisms • Each prism is composed of three struts, providing 180 struts, total • Radius of inner-tendon-layer is constrained to 80% of the radius of the outer-tendon-layer

"Tensegrity" is an elision of "tension" + "integrity" • Sphere rigidity is provided by tension elements (tendons) and compression elements (struts) • No strut touches another strut

have you read the research by Quantum Gravity Research? Their core quantum spin network model looks remarkably like your drawing. I think there must be some sort of relationship here.…

The only objective similarity is the enclosing icosahedron/dodecahedron geometry.

The Quantum Gravity Research folks employ rotations of tetrahedral "crystals" of their postulated 3D "quasi-crystal" array. My model employs 5-sided prisms, rather than 4-sided tetrahedrons.

This (my) model behaves as a rigid "exoskeleton" shell, due to tensegrity-component interrelationship. Individual prisms can not be rotated without compromising rigidity of the shell.

Maybe you're right. Perhaps I should pose my own thesis of quantum space-time, based (merely) on a pretty 3D construct.

Certain nexorades can indeed be rotated, which is what I was getting at. For example, a "dodecahedric nexorade" can be "rotated" into a "icosahedric nexorade" simply by varying the degree of the fan. I find that behavior interesting in light of QGR's tetra-rotation approach (in fact, nexorades are infinitely more "flexible" than rigid tetrahedrons as you know). My gut feeling was that there might be some sort of relationship between the two. But then again, perhaps not. Anyway, I just put it out there since it is clear you get the math (as do the QGR folks). Thanks for taking the time to respond.

Indeed, rotations are integral to the concept of nexorades (but not all tensegrities.)

You might find this nexorade animation of interest. (I use it to explain nexorades to novices.)
