Pentagonal hexecontahedron
Basic Geometry
The 5 edge lengths are:
- e1 : $ 1 $ ≈ 1.000
- e2 : $ 1 $ ≈ 1.000
- e3 : $ 1 $ ≈ 1.000
- e4 : $ \frac{\frac{1}{3} + \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{6} + \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{6}}{- 4 \left(- \frac{1}{3} + \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{12} + \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{12}\right)^{2} + 2} $ ≈ 1.750
- e5 : $ \frac{\frac{1}{3} + \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{6} + \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{6}}{- 4 \left(- \frac{1}{3} + \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{12} + \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{12}\right)^{2} + 2} $ ≈ 1.750
The 5 angles are:
- α1 : $ \arccos{\left (- \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{12} - \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{12} + \frac{1}{3} \right )} $ ≈ 118.1366°
- α2 : $ \arccos{\left (- \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{12} - \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{12} + \frac{1}{3} \right )} $ ≈ 118.1366°
- α3 : $ \arccos{\left (- \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{12} - \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{12} + \frac{1}{3} \right )} $ ≈ 118.1366°
- α4 : $ \arccos{\left (- \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{12} - \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{12} + \frac{1}{3} \right )} $ ≈ 118.1366°
- α5 : $ \arccos{\left (- 2 \left(- 2 \left(- \frac{1}{3} + \frac{\sqrt[3]{12 \phi \left(- \sqrt{-15 + 81 \phi} + 9\right) + 44}}{12} + \frac{\sqrt[3]{44 + 12 \phi \left(9 + \sqrt{-15 + 81 \phi}\right)}}{12}\right)^{2} + 1\right)^{2} + 1 \right )} $ ≈ 67.4535°
