So please enlighten me about this.
Oh, sorry, I guess I didn't make myself clear. I'm basically saying that, most likely, the woman is heads and shoulders above any of us, including me, on issues of number theory.
And thus, to her, the number "210" might have some obscure property or feature that we'd have to go to the library to look up---and then we'd still not understand it :)
But maybe I'm just dreaming :)
