Yes, they're permalinks. Also, the date is a permalink as well. Not every date in the system is a permalink, but this is a concept that occurs quite often in XF.
BTW: all you guys have replied to this thread (my thread), but I did not receive any Alert regarding your replies.

Sorry, I know this is off-topic and I think I saw a thread about this issue. But I could not find that thread.
