Hah, I immediately looked at A245783 and A241601 and wondered that the
majority of voters have a very weird taste! Until I realized that they
were already renumbered as:

https://oeis.org/A250000
and
https://oeis.org/A250001

My congrats to the winners!

I myself gave two votes for
http://oeis.org/A240926 "a(n) = 2 + L(2*n)= 2 + A005248(n), n >=0,
with the Lucas numbers A000032. " with its nice Sangaku-like illustrations,
and one vote for
https://oeis.org/A237270 "Triangle read by rows in which row n lists
the parts of the symmetric representation of sigma(n)." by Omar Pol.

BTW, the poster is very nice.


Best,

Antti
