Q: What makes the many-help-one problem difficult?

Christian Chapman Encoder $k$ informs a decoder of a source $X_k$ at rate $R_k$; $k=1,\dots, K$. The decoder seeks to recover $X_0=f(X_1,\dots, X_K)$ with high probability. Do schemes exist with failure rate arbitrarily close to 0? What aspect of this problem is not handled by the current state of the art in inf...

@Buraian Please focus your efforts on questions in the past year.
@RRL Don. And thanks for addressing my comment.
Oops, @RRL I meant the first short sentence to read "Done" (closed).
@amWhy that question is closed now.
@ParamanandSingh Gracias! Thanks for the update.

@amWhy The post I meant is the one about the claim that all mathematical theorems say nothing. The author deleted this post, undeleted it and deleted it again. Weird.

ironically speaking there is a question which asks similar on the site other than mine which existed for much much longer
1 , 2 , 3
4 , ,5
The 5th question shows no attempt and the idea in it is dupe of the one in linked.

@Buraian (1) That isn't irony. (2) If you look at the history of that question, it was not without controversy at the time. It went through at least one close cycle, has been in the close queue a few times, and is marked "Community Wiki".
@Buraian 2013, 2018, 2018; 2014, 2015. Please try to focus on newer questions. If we weren't getting hundreds of low-quality questions every day, it might be worth some effort to go back through the database and clean up older questions. However, a philosophy of triage indicates that we should focus on the new questions, which are doing the most damage in terms of encouraging users to ask more low-quality questions.
@BillDubuque Thanks for the heads up. I've deleted the partial answer.
Roomba will delete the question in 37 days. :/
@Buraian Regarding (3), the newer question is better phrased, and has more high quality answers. I have closed the older question as a duplicate of the newer.

@BillDubuque gone.

Dupe of a more general
The link you share is a better asked question, whereas your selected target lacks any context whatsoever. But I do think it is a dupe of a question, hopefully high quality, that addresses groups of prime order.
@Buraian What about selecting this is a more general dupe? math.stackexchange.com/questions/3715585/…. I can add a vote to close as a dupe of that; but absolutely the post you indicate is a dupe.
Thanks, @Buraian, for the link!
17:13
That's better yes
@Buraian Again, thanks!
1 , 2, 3
4 , 5 ,
all are the same question. I took the best out of the bunch (outside one I linked here) and VTC as dupe
18:11
@Xander ^^ regarding the dupes listed, given @Buraian's work, I closed them as dupes of this question. However, two or three of them have solid answers, so perhaps a merge can take place? Only one of the questions listed, or suggested as a target by Buraian, has no upvotes, one has no upvoted answer. Just a thought!
Thanks, again, @Buraian !
18:26
Actually, Xander, consider migrating only the answer here: math.stackexchange.com/questions/1215438/…

Little context, multiple duplicate: math.stackexchange.com/q/4400405/42969. But who cares :(
