When you skip a character, you move on to next shape.

So, 1-2-3 5-6-7 = 2 triangles

But 1 3 5 = 3 points

I think I was thrown off by the example which used 1,1,1,1 for the sphere and 2, 3 to represent isolated points. But they're consecutive. Unless I'm missing something?

ah, damn, you're right!

[charles_parnot]

fixed!

Ah ha, now it makes sense. Thanks :-)
