Just #29 ignore and skip 30 thank you!

(29) If a bounded 3D object with finitely many symmetries has an axis of order 6, then what is the strongest conclusion you can draw about its symmetry type? What is the largest number of symmetries that it could have? (30) When a bounded 3D object is properly rigidly equivalent to a thick square or a beveled square, the question marks in the flow chart (Figure 130 on page 161) indicate that we have not vet classified all the differ objects to which it
