Q: Checking my understanding of Multipliers for Difference Sets

The CountIn "Contemporary Design Theory: A Collection of Surveys," pg. 245 begins the section on multipliers of difference sets. I had previously understood a multiplier $\alpha$ of a difference set $D$ in a group $G$ to be an automorphism of $G$ which in turn induces an automorphism on the points (or b...

Bhaskar VashishthWhich is greater, $98^{99} $ or $ 99^{98}$? What is the easiest method to do this which can be explained to someone in junior school i.e. without using log tables. I don't think there is an elementary way to do this. The best I could find was on Quora, in an answer by Michal ForiĊĦek on a simil...

I am not saying that it is necessarily a bad tag. Perhaps it turns out that this new tag is useful.
But in general I do not think that it is good to retag many questions immediately after tag creation.
I'd say it is good to leave some time for other users to notice the new tag, which also gives them opportunity to post on meta, if they think that the tag should be removed. (And there are not that many posts to be removed, if the tag is not added too quickly. Not that long ago about 70 posts were bumped by adding and removing the tag when straight-lines tag was created and the removed: chat.stackexchange.com/transcript/3740/2017/1/4 )

Now it has 23 questions. At least that user slowed down a bit - so that not too many old posts are bumped in short time span.
Maybe somebody posted a comment pointing out explicitly problem with bumping too many posts...?
