Dear Sequence Fans, In the June 2016 issue of Pythagoras
on pages 20 and 21 there is a new sequence from Pim Spelier.

See http://www.pyth.eu/jaargangen/Pyth55-6.pdf

It looks like Pythagoras had a competition to
find the best sequence not in the OEIS,
and this was the winner.  I think we should
add it to the OEIS, but my Dutch is not good enough
to give a clear definition.

Maybe someone who speaks Dutch would be willing to submit the sequence (if
so, please tell me the A-number).

Thanks to Omar Pol who found the magazine (there is also an article about
the toothpick sequence A139250).
