Read a New Scientist piece by @richardelwes based on his new book Huge Numbers. There's a sidebar on subcubic graphs (as in, dots joined by lines) and a fairly simple to define sequence involving them. SCG(0) = 6. Reasonable. SCG(1) is so big you need multiple levels of special terminology to describe how staggeringly huge it is. Article also covers Goodstein's sequence. Both new to me. I ordered the book for the library where I work. This will be good reading!
