Superset Of Or Equal To Symbol
⊇ means “is a superset of or equal to,” showing that one set contains another.
U+2287
The symbol ⊇ is used to express a “superset or equal to” relationship between sets. You’ll commonly see it in math, logic, and set-theory notation. Below are practical ways to understand and copy it for documents and interfaces.
Superset Of Or Equal To Symbol Meaning
⊇ (Unicode U+2287) stands for “superset of or equal to.” It expresses that every element of one set is also contained in another set, and equality is allowed. In other words, if A ⊇ B, then B ⊆ A, and it includes the case where A and B are the same set. This symbol is especially common in set theory, predicate logic, and algorithm discussions where comparisons between collections matter. Use it when you want to communicate containment at the set level, not just a strict inclusion.
Common uses
- •State set containment with equality, such as “allowed items ⊇ required items.”
- •In set theory, write relations like A ⊇ B to indicate B’s elements are included in A.
- •Express logical conditions over collections, for example “this set of permissions includes the required ones.”
- •Document constraints in data models, where one group must cover another group (including identical sets).
- •Compare categories or feature sets in technical writing and specification notes.
Examples
⊇ Superset of or Equal To
- ⊇A ⊇ B means every element in B is also in A.
- ⊇Requirements ⊇ Must-have means all must-have items are included.
- ⊇If X ⊇ Y, then Y is a subset of X.
- ⊇A superset or equal to relation can be written as A ⊇ A.
- ⊇Allowed roles ⊇ Required roles.

FAQ
What does ⊇ mean?
⊇ means “superset of or equal to,” indicating the left set contains all elements of the right set, including the case where they are equal.
Is ⊇ the same as “superset”?
It’s the same idea but allows equality. If you want strict containment only, you typically use the proper superset symbols instead.
How do I type or paste ⊇?
You can copy it directly (⊇) from this page. It is also Unicode U+2287.
How can I include ⊇ in HTML or code?
Use the HTML entity ⊇ or the CSS escape \\2287. In JavaScript, you can use \\u{2287}.
