Triakis octahedron

Fillygon triakis-octahedron filled-corners

Basic Geometry

The 3 edge lengths are:
  • e1 : $ \frac{\sqrt{2}}{2} + 1 $ ≈ 1.707
  • e2 : $ 1 $ ≈ 1.000
  • e3 : $ 1 $ ≈ 1.000
The 3 angles are:
  • α1 : $ \arccos{\left (\frac{\sqrt{2}}{4} + \frac{1}{2} \right )} $ ≈ 31.3997°
  • α2 : $ \arccos{\left (\frac{\sqrt{2}}{4} + \frac{1}{2} \right )} $ ≈ 31.3997°
  • α3 : $ - 2 \arccos{\left (\frac{\sqrt{2}}{4} + \frac{1}{2} \right )} + \pi $ ≈ 117.2006°
