Re: [math-fun] Offset Somsky Gears, coaxial offset

I'm not comprehending some of what you all are saying. I had recently presented an argument algebraic numbers came up in Somsky gears -- and also my general purpose older argument about general bipartite planar graphs as gear configurations, will always yield algebraic numbers whenever configuration rigid. To actually find out the minimal polynomial of a given algebraic number, though, you tend to need a lot of decimals, but if you have them there are general tools to do it (using, e.g. Lovasz lattice reduction) which I presume Gosper was referring to and already knows about. -- Warren D.
