“Lisi’s inspiration lies in the most elegant and intricate shape known to mathematics, called E8 - a complex, eight-dimensional mathematical pattern with 248 points first found in 1887, but only fully understood by mathematicians this year after workings, that, if written out in tiny print, would cover an area the size of Manhattan.”
Simple? Beautifull maybe but simple, I think not.
Maybe "elegant," or "symmetrical" would be a better term.
