Phi is everywhere in this model. A slightly different version of this model lead me to notice how the product $\: \pi \Phi^3 \:$ is extremely close to a rational number. That's how I derived the approximation.

The internal structure of the Icosahedron contains 12 pentagons and the value 1/phi is the length of a pentagon vertice ( 144 degrees ) which governs all quantum processes. I have been looking for your construction, but I didn't find it. My Gravitational Constant requires that this length turns up in a Five fold geometry AND a six fold geometry (lattice packing) and here it is - thanks very much. Seems I have to look at a geometry with 30 points on a circle or tilt the hexagon surface against the pentagon surface. It seems that there is also a deep connection between your approximation and the Plank Constant - but for that you need to understand how the natural constants PRODUCED BY the lattice geometry. I would like to cite your name when I use your work, so send me an e-mail if you agree with this.

I recently became interested in Pi-Phi connection because of my fascination with the Icosahedrons 31 Great Circles and I happened to try powerings of Pi out to the 29th power and found this close approximation to the whole number 31. Pi ^ 3 = 31.0062766802998, which to me appeared to be standout from all the other powerings kinda of like a sore thumb. I'm also curious to the links between geometry and physics, if not specifically the the three stable regular Platonic polyhedra, but that is another story and hope either of you will take note of the above.

I can't think of any reasonable interpretation in which that would hold.

Hi GrG, I'm new around here and was going to use the username "GrC Tube" and changed my mind at least minute and then misspelled my chosen user name. Think I will need to contact Julien owner to change it.

I tend to think your probably correct above to that specific question,which is still relatively new thought in last day or two, so I'm just putting it out there to get broader perspective. It is a resultant of the Pi^3 = 31.00 stuff from a week or so ago that has been forefront of my cerebrum day and night recently...ha.

Thx...Rybo
