Definition talk:Polynormal Subgroup

Was the previous definition actually incorrect? Or was it just another way of saying the same thing? If the former, then those clever fellows at Wikipedia need to be alerted, because that's where the original definition came from. --prime mover (talk) 14:35, 22 April 2016 (UTC)

The previous definition was not consistent with the Wikipedia one. It had $\left\langle{H^g}\right\rangle = H^{\left\langle{H^g}\right\rangle}$ instead of $H^{\left\langle g \right\rangle} = H^{H^{\left\langle g \right\rangle}}$. --DJF (talk) 09:13, 23 April 2016 (UTC)

Okay so the notation was arguable, but the definition itself? --prime mover (talk) 10:08, 23 April 2016 (UTC)
