Sequences in the News
 January 19, 2016 Largest known term of A000043 announced: 274207281, also discovered by Curtis Cooper.
 March 2, 2014 Fredrik Johansson announces he's computed p(10^{20}), which he says is approximately 1.8381765 × 10^{ 11140086259}. Once confirmed and verified, it will be the largest known term of A000041.

Complaints
I strive to live up to the highest ethical standards. If you feel that I have wrongly rejected one of your sequences (or otherwise failed to meet the expected standards), please leave a note at Complaints About Editing where it will be reviewed. I hope that in all cases you will first contact me (through the pink comment boxes, on my user page, or by email).
