For "one-dimensional" (single-indexed) arrays – vectors, sequence, strings etc. – the most common slicing operation is extraction of zero or more consecutive elements. Thus, if we have a vector containing elements (2, 5, 7, 3, 8, 6, 4, 1), and we want to create an array slice from the 3rd to the 6th items, we get (7, 3, 8, 6).
More generally, there are d! possible orders for a given array, one for each permutation of dimensions (with row-major and column-order just 2 special cases), although the lists of stride values are not necessarily permutations of each other, e.g., in the 2-by-3 example above, the strides are (3,1) for row-major and (1,2) for column-major.

[4]: 5 Wes McKinney started building what would become Pandas at AQR Capital while he was a researcher there from 2007 to 2010. [5] The development of Pandas introduced into Python many comparable features of working with DataFrames that were established in the R programming language. [6] The library is built upon another library, NumPy.
