For 10 points, name these ideal solids which cannot be deformed.
The motion of relativistic analogs of these objects is the subject of the Ehrenfest paradox, and they are constrained by the Herglotz–Noether theorem. The motion of these objects can be described mathematically by the SE(3) group. Poinsot's (pwann-SOH's) construction can be used to visualize the rotation of these objects in the absence of torque, which can be determined by solving Euler's equations. For these objects, motion about the first and third principal axes are stable, while motion about the second is not according to the tennis racket theorem. The distance between any two points on these objects is constant in time. For 10 points, name these ideal solids which cannot be deformed.
