This holds if you fix a line l but do not fix the findable part of d.

Otherwise for every findable part of d there is an identical line.

You can also say that for every findable part of d there is a line

twice as long, if you fix d_1, ..., d_n but do not fix the line.

Why do you think it is more important or in any way preferable to fix

a line but to extend d than vice versa?
