At the moment there is no sorting so it is difficult to tell. However, if you use for-each-anchor and display the anchor's name at its position it should tell you easily enough.

The following code produces the figure below. I was able to find out the labels for the intersections anchors only by trial and error. Is there some way of getting the labels of those intersections by using a systematic and deterministic way (and not by trial and error)? Thanks!

circle((rel: (6,0)), radius: 0.5)
circle((rel: (-3,3)), radius: 0.5)
circle((rel: (0,-6)), radius: 0.5)
hide(circle((0,0), radius: 3))
})
arc-through("i.0", (135deg, 3) , "i.5")
arc-through("i.4", (45deg, 3) , "i.3")
arc-through("i.6", (-45deg, 3) , "i.2")
arc-through("i.1", (-135deg, 3) , "i.7")
for-each-anchor("i", (name) => {
content("i." + name, name, fill: white, frame: "rect", stroke: white)
})
})

Thanks, @fenjalien, for your reply! While the workaround you suggest is a nice solution when dealing with a modest number of circles, it could become cumbersome if the number of circles is very large. It might be advisable to consider introducing some form of anchor sorting. |

Yes we're thinking about it, you could make an issue about it so we could keep track. |
