The Feb issue of AMS Notices (American Mathematical Society)
contains an article of possible interest to crystallographers.

http://www.ams.org/notices/200802/
"Crystals That Nature Might Miss Creating" - Toshikazu Sunada

I confess myself perplexed as to what is actually being
described in this article. In particular, I cannot figure out
whether the "K_4 lattice" being described is truly a lattice in
the sense that crystallographers understand the term.
If so then what does it correspond to in our usual nomenclature?
