Just bought Great Stella4D. Happy to join the club of symmetrists. Having built quite a few models over the past years I am ready to tackle the compounds of 2 icosahedra as shown here:

With only trigonometry I find it rather difficult and Great Stella only presents me with the first model (from left to right), being the dual of the 2 Dodecahedra compound. Who can show me the two missing beauties in GreatStella or teach me how to bring them to life ?
Many thanks in advance.
