Thank you! Your contribution is highly appreciated and you help finding the largest possible square. Below, we describe how we proceed, in a bit more detail. (It's very simple.)

A note in advance: We will publish the names of all the people who make up the final square on this website. You can also decide to remain anonymous, after you have made your transfer. 

Now for the next steps: The search for the largest possible square will continue until March 10, 2025, 10am CET. Until then, we will contact potential donors. We may also ask you again, later, whether you want to increase your contribution if other people do so.

To avoid having to contact you unnecessarily often, we ask you to tell us the maximum amount that you would be willing to give if an equal number of people are willing to give the same amount. That is, we ask you to tell us the largest square you would be willing to take part in. 

Please take a moment to think about how much you can give, and whether you can pledge a generously large donation if others are doing the same. Your pledge will make the process quicker for you - and by making the square grow faster, you will encourage others to make generous contributions as well.

Please note:

— If the square cannot be built to the size suggested by your maximum contribution, then you will give less: only as much as corresponds to the size of the largest possible square we can find.

— If other people create a square that is even larger than the square that corresponds to the maximum amount that you have specified, then you do not have to give anything. In this case, we will contact you again. (Don’t worry, we will contact you no more than once.)

We will also notify you as soon as the search for the largest square is completed.
