Project idea: formalize error correcting codes in Mizar.

Error-correcting codes are a beautiful subject, mostly because they're linear algebra over finite fields (and linear algebra is beautiful).

But there are exceptional connections in the subject: the Golay code and the Leech lattice especially connect with disparate subjects.

To give one sense of connection, I gave Robert A Wilson's construction of the Leech lattice using the octonions as a "milestone".
