Tim's Rudimentary
Treadle Reducer
The Idea of Tekla's Proof
Like many things in mathematics, once you know the theorem, the proof
isn't hard. The idea is this: suppose we have a solution to the
problem, and that S is one of the sets in our solution. Suppose,
further, that S is used either alone or in combination to form
the targets T1,
T2,
T3, ...
Tn. Then you will still have a solution if you
replace the set S with the intersection of
the targets T1,
T2,
T3, ...
Tn.
Do this with every set in the solution, and you have a solution made of
sets, each of which is an intersection of targets.
That's the idea; I leave you to work out the details.
