Talk:Extended Cascading-E Notation

Has anyone studied this notation, and checked whether it actually has growth rate comparable to \(f_{\varphi(\omega,0,0)}(n)\)? I'm a little leary of his equations involving Knuth arrows on ordinals, and statements like "\(\omega\uparrow\uparrow\uparrow\omega = \Gamma_0\)" don't seem likely. But it's still possible that the notation has that growth rate; it's just that the Knuth arrows on ordinals is not a persuasive argument. Deedlit11 (talk) 13:42, March 21, 2014 (UTC)
