Superset Of With Not Equal To Symbol
⊋ denotes a proper superset: it includes all elements of another set, but the two sets are not equal.
U+228B
The symbol ⊋ (Unicode U+228B) is used in mathematical writing to state a superset relationship that is not equality. It’s often read as “proper superset” or “superset, but not equal to.” Use it when you want the relationship to be strict.
Superset Of With Not Equal To Symbol Meaning
⊋ means “superset of with not equal to.” In set notation, A ⊋ B indicates that every element of B is also an element of A, while A and B are not the same set. In other words, A contains all elements of B and has at least one additional element. This strict form is different from a plain “superset or equal to,” which would allow A and B to be identical. ⊋ is commonly found in textbooks and proofs, and it can be useful in formal specifications, logic, and technical writing where equality must be excluded.
Common uses
- •Writing set theory statements about strict inclusion (proper supersets).
- •Labeling relationships in diagrams or schemas where “contains all” must be non-identical.
- •Specifying constraints in formal logic or specification documents.
- •Creating math notes, worksheets, or educational materials on sets.
- •Typing or typesetting inequalities between sets in reports and technical writing.
Examples
⊋ Superset of with not equal to
- ⊋Let A ⊋ B, where B ⊆ A and B ≠ A.
- ⊋If S ⊋ T, then every element of T is in S.
- ⊋We assume X ⊋ Y to exclude the case X = Y.
- ⊋For proper containment, write A ⊋ B instead of A ⊇ B.
- ⊋A ⊋ B implies A has at least one element not in B.

How do I read ⊋ in plain words?
Read it as “superset of with not equal to,” usually meaning “proper superset.”
What’s the difference between ⊋ and ⊇?
⊋ means the sets are not equal (strict), while ⊇ allows equality (superset or equal to).
What Unicode character is ⊋?
It is the character U+228B, named “SUPERSET OF WITH NOT EQUAL TO.”
Can I use ⊋ when writing set relationships in plain text?
Yes. It’s commonly used in math notes, comments, and documentation; for formal typesetting, ensure your font/system supports Unicode U+228B.
