Compound of 30 Cubes: 30A  A5xI / C2xI  μ7
This is a compound of 30 cubes belonging to the symmetry group 30  A_{5} x I / C_{2} x I / μ, as described in H.F.Verheyen's Symmetry Orbits. The angle μ uniquely identifies one compound in the group and may vary between 0 and 45 degrees (excluding 0 and 45 degrees). For some angles 'μ' the compound has some special properties. For this compound the angle μ = acos(^{√(5+√5)}/_{√10}) and for that angle the compound can be divided into six base elements: 5  D_{20} x I / D_{4} x I, for which each order 20 symmetry axis shares an order 5 symmetry axis with the compound. The "C_{2}" in the symmetry group means that each order 2 symmetry axis of the compound is shared by two order 2 symmetry axes of two base elements.
The model itself is built with 250 gr/m^{2} Chromolux paper using the colour "pearl". This colour was chosen, because the model was a wedding present for two friends of mine. I thought it was not fitting to use another colour and I am pretty satisfied with the result. Since the model is quite small for 30 cubes it was difficult to get all the edges straight, though I don't think that my friends will complain... though ;)
