4-8-8-2 4-8-8-2 Under the Whyte notation for the classification of steam locomotives, a 4-8-8-2 is a locomotive with four leading wheels, two sets of eight driving wheels, and a two-wheel trailing truck. Other equivalent classifications are:<br> UIC classification: 2DD1 (also known as German classification and Italian classification)<br> French classification: 240+041<br> Turkish classification: 46+45<br> Swiss classification: 4/6+4/5 The equivalent UIC classification is refined to (2'D)D1' for Mallet locomotives. A locomotive of that length must be an articulated locomotive; meaning all have a joint between the first and second groups of driving wheels. All examples of this type are cab forwards.

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
