Subject: correction w.r.t. generic finite family of finite objects
Date: Fri, 27 Jul 2007 17:14:15 +0200 (CEST) [thread overview]
Message-ID: <E1IERhp-0000TX-4B@mailserv.mta.ca> (raw)
Andreas Blass has pointed out to me that that there was a mistake in my recent
mail. There does exist a global element n : 1 -> N such that G \cong K_n
(n is the order of the group G) BUT the statement G \cong K_n contains a hidden
existential quantifier over Iso(G,K_n) and this latter one is not witnessed by
a global section of Iso(G,K_n).
