I'd like some help

What is special/peculiar about the set {1, 2, 9, 10}?

It seems we can construct ALL possible positive integers from it but that's easy because we have 1.

Anything peculiar about this set? I'd be very grateful if you could tell me. Thanks

They could be the first 4 terms of an integer sequence
dictated by a(n) = n + 6[floor(n/3)]

I don't understand the question. We can construct all possible positive integers from the set {1}.

Please give us some context. What makes you think that there is anything "special" or "peculiar" about this set?
