The surface of a cube is subscribed by 4-fold 6 great circles { tori } of 3-fold tetra{4}hedron. See LINK
Proton is most stable fermionic matter humans know to exist and in Rybonics, defined by the above mentioned very stabilized 6 great circles { tori }.
Two great circles { tori } = one quark and two quarks { 4 great VE circles/tori = a meson { bosonic strong nuclear force } but two quark combinations as found VE are unstable ergo mesons are very unstable and very short lived particles.
So why is the neutron { neutral charge } differrent from the protons 6 great circles { tori }? We might ask similar question regarding neutrality of neutrinoes.
Obviously, in the case of the neutrons ---same set of 6 great circles { tori }----, it is the geometric relationship that makes them not as stable as the proton.
Since each of the 6 tori have a two flat curvature areas, ---that are halfway positions between peak positive and peak negative curvature ergo neutral { flat curvature } --- I wonder if it is way the trajectories { 0--->1--->2--->3 etc --that define each tori--- interact with other in regards to these flat neutral places, that make those 6 very stable and charged { proton } or less stable as neutron { no charge }?
Here is LINK to three kinds of Gaussian curvature........ Positive ( ), Flat { neutral }, Negative )( { aka saddle shape }
The Vector Equlibrium aka cubo{6}-octa{8}hedron via it jitterbugging tranformations will exhibit all three and other exotic shapes, in Euclidean format.
This first link shows VE jitterbugging through its icosahedral phase to the octahedral phase.
This 2nd link shows the the next phase as tetrahedron and also a flat phase.
What I dont have link to is images of the other phase transitions of the Euclidean VE that occur ee,
negative curvature, the precessed double sine-wave { see EMRadiation double sine-wave },
..this latter above can occur via two differrent ways of VE transformation
the flatten hexagon with 7th triangle tail wing, ---this is example of spacetime refusing to be 2D existence only and the 7th triangle is the erection of the hexagonal set---,
a tube via and utable set of two octahedra ---picture opening of mouth of whale shark with lareg mouth opening on two ends--,
thee complex, compound octahedron that is shaped like square from birds-eye-view and like \/\/\/\/ if it were opened into a linear set of lines,
there are others to difficult to define here. Sorry for no web page to exhibit these VE transformative exotic shapes.
