Susan,

Thanks.

I was hoping someone from the MegaDots crowd would weigh in.

FWIW, MegaDots uses a line of dots 2-5 across braille lines 9 and 18 and
with 8-1/2" width paper fits a business envelope perfectly.

Michael,

We are looking to avoid alogrithms that produce three different sizes of
section. We're aiming instead for an alogrithm that, regardless of the
number of folds, will produce sections of at most two different sizes.

There seems to be some disagreement about how to distribute the larger and
smaller sections, when the sections aren't all of the same size.

Mike is looking for a way to make this something that the end user can set.
So far, we have two preferences:

1. Put the larger section(s) first -- the smaller section(s) following.
2. Put the smaller section(s) first -- the larger section(s) following.

So far, nobody has requested the larger or smaller section(s) be placed in
the middle. This is good -- the fewer variations there are in preference,
the more easily we can understand and adapt to them.

However, let me point out a wrinkle that nobody else has pointed out so far.

If you have an even number of sections greater than two -- perhaps because
you've requested three fold lines (thus four sections) -- I posit that you
would want, if possible, to have the fold lines arranged symmetrically on
the page. This would make it possible to fold once down the middle, and once
again at the now-coincident remaining fold lines.

We wouldn't get this by putting the larger fold section(s) consistently at
the top or at the bottom. A recursive algorithm is necessary to manage such
a case well.

All of which is to beg your patience -- and that of others -- as we try to
tease out a specification on this one. We've put our thinking caps on too.

- Peter

Correct, I would want the largest section to be at the top of the page. 
Ideally, I would want the smallest section to be at the bottom of the page.
This would produce a page that has the first line or so outside of the
folded section, and still have a neat fold.

If the algorithm produces 3 different size sections, I would want the
largest at the top, and the smallest at the bottom. If there are 2 equal
size sections, and 1 larger section, I would want the larger section at the
top. If there are 2 equal size sections, and 1 smaller section, I would want
the smaller section at the bottom.
