Seventeenness

It was the first time in all the largesse of her youth that such a tone had assailed Zoe. The very seventeenness of her revolted; she dropped her attitude.

None of these descriptions seems to give you a clue to the intrinsic seventeenness of 17 – the unique feature which makes it the very number that it is.

Might not some language somewhere offer a seventeenness category that would create immediate recognition of that many items? Such a category seems unlikely, of course, and we might see it as excluded by capacity limitations on focal consciousness, limitations that would be far exceeded by a display of seventeen items.
