[seqfan] Discrepancy between definition and terms in A257481?

[Felix Fröhlich]

Dear SeqFans

the definition says "a(n) is the maximal number of circles that can be
enclosed by a chain of n circles". So why does the example say "For a(7),
one circle can be completely enclosed by six surrounding circles"? Isn't
that an example for the value of a(6)? Same goes for the example for a(10).
Shouldn't a(10), by the definition of the sequence, give the maximum number
of circles that can be surrounded by a chain of ten circles? Or am I simply
completely misunderstanding something about the sequence? Can someone
clarify how the definition, example and terms of the sequence correlate to
each other?

Best regards
