[seqfan] Donald Knuth Turns Eighty

[Peter Luschny]

We could make him happy and calculate some more terms of
https://oeis.org/A285357 and https://oeis.org/A285361

Don suggests that one might look at a few conjectures about
set partitions and generating functions that he has put online at
http://www-cs-faculty.stanford.edu/~knuth/caspagf.txt

And be sure to use triangular paper when you write your
solutions down!  https://goo.gl/4twPnf

Happy birthday, Don!
