v1 v2 3 3 Sequence is a general notion of an ''Ordered'' onedimensional structure. (Tables and Threes are usually 2d structures, while graphs and molecules are 3d structures). 4 4 5 The canonical example of a sequence is a {{{List}}} which is considered as a linear structure made out of pairs. {{{Pair}}} itself is an kind of an Ordered Sequence  it is a linear structure of exactly two elements with an explicit order. The [wiki:/AbstractDataType ADT] consists of {{{cons car cdr pair?}}}.5 The canonical example of a sequence is a {{{List}}} which is considered as a linear structure made out of pairs. {{{Pair}}} itself is an kind of an Ordered Sequence  it is a linear structure of exactly two elements with an explicit order. The [wiki:/AbstractDataTypes ADT] consists of {{{cons car cdr pair?}}}. Logically, Pair is a specialized instance of more general (and more abstract) type of Sequence, which implies ordered linear structure. 6 6
