It ' s not possible through any means . We can write down infinitely many different matrices X such that XY Z . It ' s impossible to solve for X , because that would imply there ' s only one solution . You could write XYZ as an underdetermined system of linear equations in the entries of X , and get an expression with free variables in it that way . <| sep |> They weren ' t nazis . <| sep |> Thanks ! I You ' re right , of course . I think I was picturing an artificial grav environment , my kid kept insisting i was building Deep Space Nine . It ' s just a prototype anyway . The trick was learning to use the rotate and offset tools ! that and 4 x symmetry <| sep |> Unfortunately it seems the realistic part is all the game has going for it .
