E8 Structure Decoded
arobic writes "A group of mathematicians from US and Europe succeeded in mapping the E8 structure, an example of a Lie group. These were developed by the well-known mathematician Sophus Lie (pronounce Lee) in the last century and are used for many applications, mainly in theoretical physics. This is an important breakthrough as it could help physicists working on Grand Unified Theories (aka GUTs)."
The magnitude and nature of the E8 calculation invite comparison with the Human Genome Project. The human genome, which contains all the genetic information of a cell, is less than a gigabyte in size. The result of the E8 calculation, which contains all the information about E8 and its representations, is 60 gigabytes. This is enough to store 45 days of continuous music in MP3-format.
Hear that? That's the sound of Apple's iPod marketing finally reaching absolute ubiquity.

Pronounce it "Lee-eh"; At least that is how I would do it as a Scandinavian.
It's PRINCESS "Lee-eh" you insensitive clod!
Help! I've fallen in a karma hole and I can't get up!

Because we know physicsts and mathematicians that would be interested in this problem would have no idea how a computer works and have to translate it into teenager speak.
God spoke to me.
is, of course the third worst in the universe.
So now we're going to have truth and lie tables?
Stop this crazy planet. I want to get off!

CAT: [to RIMMER] What IS it?
RIMMER: It's a rent in the space-time continuum.
CAT: [to LISTER] What IS it?
LISTER: The stasis room freezes time, you know, makes time stand still. So whenever you have a leak, it must preserve whatever it's leaked into, and it's leaked into this room.
CAT: [to RIMMER] What IS it?
RIMMER: It's a singularity, a point in the universe where the normal laws of space and time don't apply.
CAT: [to LISTER] What IS it?
LISTER: It's a hole back into the past.
CAT: Oh, a magic door! Well, why didn't you say?

the answer is 42!
Sadly, Mr. Vogan was later lynched by a rampaging mob of respectable physicists who had finally realized that the one thing they really couldn't stand was a smartass.
How can I believe you when you tell me what I don't want to hear?
Mine goes to E_11.
Don't trust anyone under thirty.
Lee-eh! L-E-E--E-H! L-E-E--E-H!
Poor mathematician. He must've been killed by Snu-Snu. Or maybe lucky mathematician...
Would you kindly mod me +1 insightful?
Typical geek attitude. If it's not Vorbis, it's LAME.

E8 is not a Lie Group. E8 is the biggest Lie Group.
:D
It seems somebody flunked basic set theory.

As other had said it is not the biggest Lie group, there are two families Ak and Dk of lie groups which are infinite sequences. You can think of Ak as the symmetry of the trianagle, tetrahedron, 4-simplex, ..... there one of these for each dimension. Likewise Dk is related to the symetry of the square, cube, hyper-cube and n-dimensional cube. To these are added the so called exceptional groups, sort of like the icoshedron and its four dimensional analogue. It just so happens that these do not for an infinite sequence, higher dimensional spaces kind of get simpeler after a while which don't allow for E_11 to exist.
