E8B

E8B may refer to several different things across fields, including mathematics, transportation, biology, or model designations. To provide a precise, wiki-style article, could you specify the intended domain for E8B? For example, is it a mathematical object (such as a variant of a root lattice), a transportation route designation, a gene or protein name, or a product/model name in another field? Once you indicate the domain, I can generate a concise, neutral article under 300 words.
