# How many dimensions is E8 lattice?

## How many dimensions is E8 lattice?

8 dimensions

This lattice, sometimes called the “8-dimensional diamond lattice”, has a number of remarkable properties. It gives most efficient sphere-packing in 8 dimensions, and is also the unique even, unimodular lattice in 8 dimensions.

## What is E8 in physics?

“An Exceptionally Simple Theory of Everything” is a physics preprint proposing a basis for a unified field theory, often referred to as “E8 Theory”, which attempts to describe all known fundamental interactions in physics and to stand as a possible theory of everything.

**What does E8 mean in physics?**

E8 manifold, mathematical object with no smooth structure or topological triangulation.

### What does E8 mean on air conditioner?

The E8 error code means that your air conditioner is operating under extremely high heat and humidity and that it is having an impact on its performance.

### What is E8 in Panasonic AC?

What Does Error 8 mean? If you have a mini split air conditioner, an error 8 will occur when there is a fan speed malfunction. Mini-splits have an indoor air-handling unit or evaporator and an outdoor condenser or compressor.

**What is E8 in induction stove?**

Induction hob displays error message E8 or E822. It indicates the appliance is connected to one phase only.

## What does E8 mean after a number?

The speed of light in one such example is shown as: 3.0 x 10^8 or 3.0E8 Where 10^8 stands for 10 to the 8th exponent and 10E8 means the same.

## What is E8 in Voltas AC?

An E8 error usually indicates a fan problem with the indoor or outdoor unit. An E8 error is usually cleared by power cycling both the indoor and outdoor unit by turning power off at the breaker. Be sure to check the indoor air filters are not dirty and blocking air flow from the fan.

**What does E8 mean on a window AC unit?**

### What are the names of the different shapes?

Shapes Names | Geometric Shapes 1 Triangle 2 Right triangle 3 Scalene triangle 4 Rectangle 5 Rectangle 6 Parallelogram 7 Square 8 Rhombus 9 Oval 10 Pentagon

### What is the dimension of E 8?

The E 8 algebra is the largest and most complicated of these exceptional cases. The Lie group E 8 has dimension 248. Its rank, which is the dimension of its maximal torus, is eight. Therefore, the vectors of the root system are in eight-dimensional Euclidean space: they are described explicitly later in this article.

**What is an e 8 algebra?**

The designation E 8 comes from the Cartan–Killing classification of the complex simple Lie algebras, which fall into four infinite series labeled A n, B n, C n, D n, and five exceptional cases labeled E 6, E 7, E 8, F 4, and G 2. The E 8 algebra is the largest and most complicated of these exceptional cases.

## What is the meaning of E8×E8?

E 8×E 8 is the gauge group of one of the two types of heterotic string and is one of two anomaly-free gauge groups that can be coupled to the N = 1 supergravity in ten dimensions. E 8 is the U-duality group of supergravity on an eight-torus (in its split form).
