But I suppose very few users have actually taught discrete logs, so probably many readers don't appreciate such pedagogical subtleties. Oh well...

@RRL But they're already all gone.

For deletion:

@Saad: Thanks. I’m not sure now which ones I was referencing. No matter. I try not to list new candidates until older ones have been considered. By the way are we still following that “rule of 16”? It seems that only three of us regularly post these.

@RRL Rule of 16? I don't know that rule actually. One of the CRUDE member is in suspension, though.

@Saad: Yes — that member suggested that we each limit the number of proposed deletions and closures to 16, i.e. 16 deletions and 16 closures — to which we agreed. Don’t ask me why the number 16 was chosen. I suppose it is about right given the daily allocation of deletion votes among the members here who participate in this activity. So I shall continue in that way unless I see less participation from others. Thanks.

@RRL Now I see that. Although 16 closures are far below the daily quota of 50, I've hardly ever seen that 16 has been reached either.

Very poor answer (to a good question).

What was wrong with math.stackexchange.com/questions/3137898/… ? OP did mention some work (using Lagrange). There isn't much work you can do on such a problem short of getting the right idea.

@darijgrinberg "Mentioning" some work is not the same as actually showing some work. Moreover, as I have repeatedly said in the past, an "attempt" is hardly better than no context at all. To someone who does not work with rings on a daily basis, there is a lot of context missing. For example, it is not even clear to me that every ring has a "2" in it---clearly defining which rings are being discussed would be helpful. Recalling "Lagrange" would also add context.

another thing that can be fixed in an edit

A reference to the source of the problem would also provide context. For example, if the exercise is an exercise from a book, knowing what book it comes from would help.

@darijgrinberg But the user did not make those edits.

there, fixed it

Between the time that the question was closed and the time that it was deleted, the original asker had three weeks to fix the question. They didn't, thus it was deleted.

once again, you're coming from the wrong point

this is not about the question but about the answers
