173_RT_2.7527

2 f^2/Sqrt[1+f^2] = 2.75276

Ez az 1 élű RT laptávolsága. This is the distance of two opposite faces of RT having edge lenght 1. RT with face cobnection can be placed at the vertices of many polyhedra (How many?) E.g. 12 RT at vertices of ico, with RH in the middle.

172_12ico_fractal

12 ico(sahedra) are assembled with edge-to-edge connection at the vertices of another ico. An enveloping ico is attached, and then the process is repeated to from fractal ico.

 

171_RHatBucky

RHs are placed to vertices of Truncated Icosahedon, and then RHs and TRs are added.

170_RH32RT

32 RH are placed at the vertices of a and RT. The geps are filled with RTs, or pairs of RT and RH

Sándor Kabai - January 12, 2010

Challenge: Calculate the height of tower consisting of n RHs placed on each other, where each RH is reduced by the golden ratio relative to the previous one.

20 RT at the verices of dodecahedron and 12 RH at the vertices of icosahedron. Pleasantly matching each other, producing a sealed internal space. ... but what is this space look like?
