"Papyrus"-Class Armored Lint Transport

The completed boat now only exposes one surface to the harsh environment (increasing survivability when constructed with one-side-glossy photo paper). All loose flaps have been stowed below decks. I toyed with an invisible change that would have made the design mirror symmetric about two planes (now only rotationally symmetric about 1 axis) at the cost of adding a few hidden folds. Symmetry or simplicty??? It was a really tough decision but I went with simplicity. Maybe when I iterate with a square piece of paper instead of normal letter size I can incorporate more symmetry without adding too much complexity.

class notes?

It is actually some notes regarding a compact (at least in intention) mapping of the space of all SAT problems onto the the natural numbers. The tricky (unsolved) part is making the mapping order and assignment invariant so that... 11* *00 101 and (first two columns inverted and flipped then the rows scrambled) 1*0 101 00* will map to the same number. The naive approach (numbering subsets of all fixed-length trinay strings along the increasing diagonal) explodes quickly.
