It seems that the difference between Polydoughs and toruses is that the poly-gone shape means you can use a spanner to apply torque when a polydo doesn't (talk, that is)
Hi Tofique, Mathematicians normally come across donuts in the context of topology, but, all your polydos are identical to an ordinary ring donut in that context. Have you discovered any properties of them which are not covered by the study of other solids (platonic etc.)?
