I meant the arrangements, not the sets. One could have also divided by two directly in the first condition. And the snake for AND is certainly not standard.I think this is a fairly standard form of the set-builder notation. https://en.wikipedia.org/wiki/Set-builder_notation#Examples

Sorry. I misunderstood what you were objecting to. Now I see that you were referring to the calculations. I assumed that the "snake" is just meant to separate the two columns of calculations, not a mathematical symbol.I meant the arrangements, not the sets. One could have also divided by two directly in the first condition. And the snake for AND is certainly not standard.
