Amicable Pairs (How many have been found so far?) My question is simply, how many amicable pairs have been found so far using super computers?
I have been trying to find any kind of answer online that is up to date, but after searching in depth I can't find any academic papers (or google results for that matter) that date past 2009.
Have people given up on finding these numbers because they have minimal use in mathematics?
 A: There is a list of known amicable pairs, perfect numbers, sociable numbers, etc. here.  This is the most up-to-date  list of amicable numbers that I know of, although, unfortunately, it has not been updated since September 28, 2007.  It lists 11,994,387 amicable pairs.  According to the site, the list is exhaustive for $a<10^{14}$ ($a$ being the smaller member of an amicable pair), and there are $39,374$ such pairs.
2015 update: The link I gave above in 2012 no longer seems to work, but there is now another copy of this data (in a somewhat different format) here.
A: There  is a database of amicable numbers hosted by Eastern Kentucky University. 

The known amicable pairs are arranged in separate files according to the number of digits in the smallest member (3 digits - 999 digits and those with 1000 or more digits in one file). 

A: There are 1.2 billion amicable pairs known and listed at sech.me/ap/
The host of the website encourages anyone to join the search for new pairs
as volunteers in the BOINC project (much like the GIMPS project).
Volunteers are finding new pairs daily.
