The lattice

E8 and the Gaussian code

Let [formula in source] be the Construction-A lattice of [formula in source] CS99, with the standard inner product [formula in source] of [formula in source] . Then [formula in source] , and since [formula in source] is doubly even, writing [formula in source] with [formula in source] a codeword lift gives so every nonzero [formula in source] has [formula in source] : the minimum of [formula in source] is [formula in
