A yin yang puzzle is made into an square-shaped grid. Given that there are exactly 84 white circles in the solution, how big is the grid and how many of the white circles are located on the edge of the grid?
If you're unfamiliar with yin yang, see for example https://www.cross-plus-a.com/puzzles.htm#YinYang
(solving Loop Area Problem first may or may not make this one easier, depending on your approach)
Solution code: The size of the grid (i.e. how many cells are there in each row/column), followed by the amount of white circles on the edge.

Von mir auch danke für das Rätsel.
Ich habe es mehr heuristisch gelöst, aber jetzt habe ich auch eine Beweisidee.

What a silly mistake. I came up with the solution but couldn't count the cells right. Thanks for the nice puzzle!

@WvdWest: Your solution is correct, the code is wrong. Count again.
