Capital Proximity

Offhand the closest two distinct national capitals I can think of are Kinshasa (Democratic Republic of the Congo, formerly known as Zaire) and Brazzaville (Republic of the Congo), which are located opposite each other on the banks of the Congo river. While the river has some breadth I expect the townships border each other. If you want to split hairs you could measure the distance from the capital building of each to get a distance.

So... anyway for the sake of this exercise... what are smallest distance between three national capitals? To define this we'll imagine a triangle connecting the three and take its... perimeter. I put it this way so if by some miracle three capitals are in a perfect line we don't get someone trying to say that triangle has zero area. Just add the distance from capital A to capital B, then B to C, then C back to A. That is your combined distance.

As part of this exercise we can repeat this with four capitals.. and five.. and so on.

But let's just focus on the 3, 4 and 5 for now. Some of them might be the same. I would imagine we'd be looking at smaller nations here, perhaps in carribean isles. I have not looked this up yet, am just posting it then hopefully will answer later. Since I'm getting almost no responses to things here I'll cross-post this in e-sam and maybe copy some of the replies back to here.
