[seqfan] Number of arrangements of n lines in the plane, A241600

[Neil Sloane]

Dear Seq Fans,
Max Alekseyev and I were looking at this question.
I computed the first five terms, by hand, so they are
probably wrong. To get the ball rolling, I created A241600.
Comments and corrections are welcomed!
Neil
