[seqfan] A true Mac Mahon ruler?

[Éric Angelini]

Hello SeqFans, 
The first 8 terms of A002049 are:
1,3,7,12,20,30,44 and 59.
I see that I can measure 29 in two
ways with this ruler (I thought only
one way was authorized):
30-1=29
59-30=29
I am obviously missing smthg as this
is an ancient seq. signed by Neil himself.
Anyway -- is it possible to build a
wooden ruler with as few as possible 
vertical marks such that all integers 
measures between 1 and 200 can
be materialized only once?
I guess this sort of question is as
old as the hat I'm wearing right now to 
avoid the killer sun we currently have
in Brussels. Forgive me.
(and if this seq is already 
in the OEIS, my shame will
be complete).
Best,
É.
