Feb 13, 2019 at 18:09 comment added Qfwfq @wonderich: done. In general, to ruturn to a previous version of the question all you have to do is click on the "edited [time] ago" link on the bottom of the OP (just on the left of your icon) and select the version you want to roll back to and click "rollback".

Feb 12, 2019 at 23:13 comment added Theo Johnson-Freyd @Qfwfq I've certainly seen the notation $G \times_N H$ for this, and I have not seen $G \times^N H$. Although I agree the latter is more consistent with other established notation, the former I think is more standard... I think it is coined from a balanced tensor product $M \otimes_A N$?
Feb 12, 2019 at 20:29 comment added wonderich ok, then, thanks, please upvote too to get us some attention!
Feb 12, 2019 at 19:36 comment added Qfwfq [uhm, just changed the notation for "twisted" product $G\times^N H=(G\times H)/N$ cause when I see $G\times_N H$ I tend to think of a fibered product; of course if you don't like the notation change you can revert it back!]
