Great Stellated DodecahedronGreat Stellated Dodecahedron is one of semi-regular solids. First discovered in 1568 by Wenzel Jamnitzer, it was rediscovered by Kepler (and published in his Harmonice Mundi in 1619), and the again by Louis Poinsot (1777-1859) in 1809. It belongs to the class of Kepler-Poinsot solids The great stellated dodecahedron is beilt on top of a regular icosahedron by attaching a triangular pyramid to very face of the latter. It follows that a great stellated dodecahedron has 32 verices, 90 edges, and 60 faces. Euler's theorem is again quite easy to verify.
Drag the mouse to rotate the dodecahedron. Use the right button to remove and put back individual faces.
