I thought the easier way of disseminating decent mathematical news would be with a structure as in MO Q&A. Thanks for the replies.

AMS has a math news email list. So perhaps that is where a math news twitter would best fit?

I looked there and didn't find one, although there is one for "joint math meetings 2011"

It's possible to do this on twitter itself. There is already the functionality of "lists", whereby somebody can bundle a bunch of twitter feeds together, and then anybody can follow the bundle. The only obstruction to being exactly what you want is that there doesn't seems to be a public/vote-based way to grow or trim such a list. A passable solution is to have a twitter account (say twitter.com/mathlist) with access shared by a group of moderators. If somebody wants a feed added/removed from the list, they could simply (re)tweet "@mathlist please add/remove @xyz to/from [list-name]".

Any takers?

@Elohemahab,

probably not! Why should such a news page exist at MathOverflow rather than somewhere else on the web? Who would maintain it?

My main objection is simply that MathOverflow exists for a very particular purpose (I know, I know, half of everyone here disagrees, but still): to provide a place where technical mathematical questions can be quickly asked and answered by experts. Disseminating news is pretty tangential to that.

Thanks. I'll post it again.

If you were asking for the number of isomorphism classes of subgroups to be the same then the answer Z4 and Z2xZ2 was ok. But if you ask for the number of subgroups to be the same (Z4 has three subgroups and Z2xZ2 has five) then I don't see a simple counterexample (though there probably is one even with abelian groups). I was curious to know if there is a simple answer to the second question.

It has a simple answer and I regret posting it.

Not related to your question, but why did you delete the question about "group reconstruction"?

Twitter does best to disseminate news instantly but when it comes to “math on twitter,” I have the problem of not knowing whom to follow so that I keep abreast of recent developments in math (both general and specialization-specific). So is there any chance a news page will be added where users add decent news and remove indecent ones? I hope moderators would give this a serious consideration.
