2-8-8-8-8-2 2-8-8-8-8-2 Under the Whyte notation for the classification of steam locomotives, a 2-8-8-8-8-2 has two leading wheels, four sets of eight driving wheels, and two trailing wheels. Because of its length, such a locomotive must be an articulated locomotive. It is not longer than a normal articulated; the fourth set of drivers is located under the tender. Other equivalent classifications are: UIC classification: 1-D-D-D-D-1 (also known as German classification and Italian classification) AAR classification: 1-D-D-D-D-1 French classification: 140+040+040+041 Turkish classification: 45+44+44+45 Swiss classification: 4/5+4/4+4/4+4/5 The equivalent UIC classification is to be refined to (1'D)DD(D1').

1/2 + 1/4 + 1/8 + 1/16 + ⋯ meters, and so on Zeno argued that the tortoise would always remain ahead of Achilles. The parts of the Eye of Horus were once thought to represent the first six summands of the series. 1/2 + 1/4 + 1/8 + 1/16 + ⋯ In mathematics, the infinite series is an elementary example of a geometric series that converges absolutely. There are many different expressions that can be shown to be equivalent to the problem, such as the form: 2 + 2 + 2 + ... The sum of this series can be denoted in summation notation as: As with any
