[seqfan] Re: A new sequence in Dutch magazine "Pythagoras"

[Neil Sloane]

By the way,  what about the other new sequences in the same Pythagoras
article? See "Andere Rijen" - can someone explain what they are?  (And then
they too should be added to the OEIS.)
(Here is the link again: http://www.pyth.eu/jaargangen/Pyth55-6.pdf  See
page 21)

Best regards
