Okay, GPT4 said there a just 189 non-overlapping 50km bands (horizontal, vertical, and diagnoal) in Europe and then continued to calculate the chance to land those 7 points in any of the 189 bands and gave a result in the order of 10^-12.

You could have two points in 2 of your non overlapping bands that are less than a band's width apart.

Also, the probability of the first 2 points will always be 100% because they define the line.

Also, it's not 7 random points, it's 7 of thousands of random points.

Ah - I missed this one.

Alright, I suppose it's not as simple to formulate the question accurately and correctly.

But diagonal at what angle? :)

I think if you set the probability of the first one at 1, then the rest works perfectly at any angle of band. I could be wrong, but intuitively that seems correct.

search box tells me 600 choose 7 is 5e15, which implies (if google and GPT4 were correct) that there ought to be on the order of thousands of fat lines containing 7 actual cathedrals
