comment If $X$ is $G$-paradoxical then $G$ is $G$-paradoxical. Is my proof correct?
Sorry if I did not read it in detail, but I guess all is well. And I guess my old hint is acceptable. But, as noted, we are now working on a second edition so if you see anything that is obscure, or could benefit from an elucidating phrase, (or is wrong!) please tell me. You can find my e-address atop by web page, stanwagon.com
