Is that repetition of the source accidental or on purpose? --Jshflynn (talk) 01:50, 9 March 2013 (UTC)


 * Purpose. You can see how each of them has different prev/next and a different section number. It happens sometimes. &mdash; Lord_Farin (talk) 09:06, 9 March 2013 (UTC)


 * Clark does that sometimes. It's almost as if he forgot he'd already brought the subject up earlier. --prime mover (talk) 09:09, 9 March 2013 (UTC)

Better: $G$ is referred to as an ETG rather than is an ETG. (Every group is an ETG for some action.) Clark's use of language in that section is not very precise. --barto (talk) 11:24, 15 July 2017 (EDT)


 * "for $\phi$" -- better again? --prime mover (talk) 11:27, 15 July 2017 (EDT)


 * Yes, fine. (Clark uses "of $X$", but that's still ambiguous. It's really $\phi$ what this is about, not so much $G$ or $X$.) --barto (talk) 11:31, 15 July 2017 (EDT)
