Basic Examples  (1)

Sort lists using lexicographic order:

Shorter lists are ordered first in canonical order:

Scope  (5)

Sort lexicographically the elements of a list:

Use an ordering function to compare respective subexpressions of the elements:

Sort lexicographically expressions with heads other than List:

Sort lexicographically a list of strings:

Sort lexicographically a list of associations, comparing respective key-value pairs:

Applications  (1)

Properties & Relations  (6)

Order is determined by the first element that differs, regardless of expression length:

When all elements coincide up to the shortest length, shorter lists are ordered first:

Empty lists are sorted before any other list:

LexicographicSort[list] is equivalent to Sort[list,LexicographicOrder]:

Compare with canonical order:

For lists of the same length, LexicographicSort is equivalent to Sort:

LexicographicSort with strings is equivalent to AlphabeticSort with default options:
