Define an "alphabet" as follows. Consider a grid of six nodes in a 2x3 grid (inspired by Braille). Consider all the graphs possible by drawing subsets of straight edges between nodes. So far, this is the same as the kanji or net idea from earlier.
Next, for any totally unconnected node, we have the choice of marking it with a dot or not, kind of like dotting the letter i (or not, like in Turkish).
Require that the top left node always be used, either as a dot or as part of an edge. This avoids letters looking the same due to translation. There still remains a problem with pairs of letters.
How many letters are there?
