Remarkable Sequences from the First 400,000 Entries in the OEIS
To celebrate the On-Line Encyclopedia of Integer Sequences reaching 400,000 entries, which should happen this month, I will describe some of the highlights of the database, including the scariest sequence, the most musical, the funniest, the best rug design, the best and the
worst contributions from AI, the most wanted prime, the most wanted proof, the shortest and the longest finite sequences, and the hottest new sequence.

Hello Neil,
I’m happy for this gathering reminding me such good moments shared with you and Eric Angelini !!!
Unfortunately, I will not be able to follow it live, nor the social after, for good artistic reasons : we have an important rehearsal for a concert to come.
I hope your gathering will soon be published on line and visible these days!
We still miss Eric ; there is a little WhatsApp group of friends and his family in hommage to him, maintaining his way of exchanging news about art and science.
I wish you a very good gathering and “after”.
Alexandre from Brussels
I am eagerly waiting for the presentation by N J A Sloane. I have contributed more than 650 integer sequences to OEIS. I have covered his youtube video on “The most wanted Prime Number” in my LinkedIn post below:
