Side Set \sideset

When to use Side Set

Places additional scripts on the sides of a large operator. In source, start from the exact \sideset command instead of imitating the rendered glyph with Unicode characters or manual spacing. This keeps the expression editable and gives the renderer enough structure to apply mathematical spacing correctly.

Syntax

\sideset

The documented syntax belongs to amsmath. Keep every required argument, brace pair, and environment boundary intact when moving the command between an editor, Markdown processor, notebook, or publishing system.

Example

\sideset{_a^b}{_c^d}\sum

Rendered output

four-sided sum scripts

Copy and compatibility checks

• Copy \sideset exactly; changing its case or removing a leading backslash can turn it into plain text.
• Confirm that the destination loads amsmath before relying on this command.
• Render the example once, then inspect grouping, limits, scripts, and spacing before publishing.
