Relation symbols in LaTeX

42 commands, each with the package it needs

Symbol reference, latexci

Abstract

Symbols that compare two terms, such as \leq and \approx. They get a thick space on each side, and a long inline formula may break after them. Table 1 lists every symbol of the category with its rendered glyph, the command to type and the package to load; each name links to a page with a worked example, and 8 of them to a note comparing the commands that compile.

Table 1. Relation symbols in LaTeX: glyph, command, package (none means built into LaTeX) and the page for each symbol. Commands go inside math mode unless the page says otherwise.

The same table exists for every family of symbols. To find one by name or by pasting the character, use the symbol search.
