You call it "fetus in fetu", but does anyone else? I've never heard that medical term used for this kind of life in Go (instead "false eye life", DoubleHeadedDragon, snake/dragon eating its own tail) and I don't see the allusion of a little version of something living in a bigger one: the 2 false eyes are equal in importance. So I'd suggest calling it by a more familiar name.

After I have discovered the property of omitting corner stones in the squares as being equal to the number of connections to other squares, I would no longer refer to eyes as being false. I would rather say that there are too few connections to other squares or too many omitted corner stones
