(explanation: the "single letter column" above the
four "|", here (the "flagpole"), spells vertically
O N E S E V E N ... which is the sequence itself).
In extending the sequence, always try to use the
smallest Natural not yet present in the sequence.
Is the sequence a permutation of the Naturals?
Best,
É.
(there is a follow-up post coming with numbers only)
