Could any one kindly inform me as to the site where one can get table of partitions from 1 to 100? Tks

You can compute any partition number using my ECM factoring applet and then entering P(n) for the partition number n. For example P(100) = 190569292.

Better yet, scroll down the page so you can see the "Batch factorization" window. Then enter the expressions P(2), P(3), P(4), ..., P(100) in the upper pane one per line and then press any of the buttons below (except of course "Clear boxes").

You will see the numbers in the lower pane.

You can check http://www.asahi-net.or.jp/~KC2H-MSM/mathland/part/ which has them upto 30.000

This site also keeps track of all known factorizations of partition numbers.

I tried your suggestion for p(12) and p(81);it is not working.Should I wait for about 10 minutes?

No, it takes a few miliseconds.

Can you do other factorizations?

Notice that in order to work, the page needs both Javascript and Java enabled. It is possible that you do not have the Java Plugin installed. In that case, just go to http://www.java.com/ so you can download it.
