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.

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

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.
