What's the name of that "intruder" galaxy ? Seems to be that eliptical galaxy w/ no spehrical arms and no band at the center.. And, surprisingly, it passed through this main galaxy, triggered such violent destruction/displacement as well as creation but on looks almost untouched in it's own appearance (except floating connecting gas clouds that give away the secret). As if it has nothing to do with this chaotic impact triggered and left behind. Unless someone researches the interaction and proves that that it was culprit, normally no one would have a slightest doubt that it caused such havoc.. Right ? So interesting..
Well, clearly AM 0644-0741 has taken a hit that made it throw out all that gas and dust that subsequently formed a fantastic lopsided starforming blue ring around the main body of AM 0644-741, which, by the looks of it, started out as a barred grand design (that is, two-armed) spiral galaxy.
In my opinion, the most likely galaxy to have passed through the disk of AM 0644-741 and turned it into a ring galaxy is the galaxy that I have labelled 5 in my annotated image. The number 5 galaxy is smaller than AM 0644-741, it appears to be at the same distance as AM 0644-741 (because it has the same overall color profile), and it seems to lack any outer features (which were presumably ripped off during its passage through AM 0644-741).
Interestingly, there are some similarities between AM 0644-741 and NGC 7318B in Stephan's Quintet.
What are the names of the galaxies close to AM 0644-741? I have absolutely no idea. Please note that with a name like that, AM 0644-741 itself is sure to be very faint and far away. The same goes for its neighboring galaxies, but they, unlike AM 0644-741, are not interesting in themselves and are sure to have their designations listed only in more obscure and hard-to-access catalogs of faint galaxies.

P.S. Have to edit my post to note that I now have a nice palindrome number of posts, namely 11411 posts. I like it!
