Multimap Symbol
⊸ is the multimap symbol (U+22B8), used to denote mappings that relate one input to multiple outputs.
U+22B8
The symbol ⊸ is called the multimap. It’s commonly used in math and related writing to express “one-to-many” mapping behavior. You can copy it directly or use its Unicode, HTML, CSS, and JavaScript forms.
Multimap Symbol Meaning
⊸ (Unicode name: MULTIMAP, code point U+22B8) is used to indicate a multimap: a mapping in which a single input can correspond to multiple possible outputs. In practice, this notation appears when you want to emphasize that the relationship is not strictly one-to-one or one-to-single-output. Depending on the context, it may describe structures like relations, set-valued functions, or other frameworks where an input can generate a collection of results. When writing papers, documentation, or technical notes, it helps communicate “one input, many outputs” clearly in a compact mathematical symbol.
Common uses
- •Representing a multivalued or set-valued mapping in math notes and documents
- •Writing “one input maps to multiple outputs” in technical explanations
- •Labeling relationships in diagrams or schema documentation for non-unique mappings
- •Denoting multi-output transitions in formal or computational models
- •Clarifying notation in textbooks, slides, and academic communication
Examples

- ⊸Let f ⊸ be a multimap from X to Y.
- ⊸An element x ∈ X corresponds to several values in Y via ⊸.
- ⊸We define g ⊸ h as a relationship producing multiple outputs.
- ⊸For each input, the multimap assigns a set of possible results.
- ⊸In this model, input a ⊸ outputs include b and c.

FAQ
What does ⊸ mean?
⊸ is the multimap symbol. It typically indicates a mapping where one input can correspond to multiple outputs.
What is the Unicode information for ⊸?
The Unicode name is MULTIMAP and the code point is U+22B8.
How can I copy ⊸ into my code?
You can use the Unicode character directly, or use HTML entity ⊸, the CSS escape \\22B8, or the JavaScript escape \\u{22B8}.
Is ⊸ the same as a normal arrow?
Not exactly. A regular arrow often suggests a single target, while ⊸ is used to emphasize multi-valued (one-to-many) mapping.
