Can anyone solve, or help me to solve a practical problem that I have.
I have a rectangle which is 400mm by 300mm, I need to pack 40 equal circles of diameter 45mm onto this rectangle. I need to maximise the minimum distance between the circles. Another way of putting this is to say that I want the 40 circles to be as far away from each other as possible but still fit into my rectangle. Can anyone help with this?
