Zermelo-Fraenkel axioms of set theory
- Axiom of Extensionality. Two sets are the same set if they have the same elements.
- Axiom of Regularity. Every non-empty set x contains a member y such that x and y are disjoint sets. This implies, for example, that no set is an element of itself and that every set has an ordinal rank.
- Axiom Schema of Specification. The subset of a set z obeying a formula ϕ(x) with one free variable x always exists.
- Axiom of Pairing. If x and y are sets, then there exists a set which contains x and y as elements.
- Axiom of Union. The union over the elements of a set exists.
- Axiom Schema of Replacement. The image of a set under any definable function will also fall inside a set.
- Axiom of Power Set. For any set x, there is a set y that contains every subset of x.
- Well-Ordering Theorem. For any set X, there is a binary relation R which well-orders X.
Also:
- Axiom of infinity. Let S(w) abbreviate w ∪ {w}, where w is some set. Then there exists a set X such that the empty set ∅ is a member of X and, whenever a set y is a member of X, then S(y) is also a member of X.
Implicit math: Sets are simplexes. Are simplexes defined by their subsimplexes as well?
- Well-ordering theorem. Each vertex is related by edges to the other vertices. Established by the q-weight.
- Axiom of power set. The power sets are the lattice paths in Pascal's triangle.
- Axiom of union. Simplexes combine to form larger simplexes.
- Axiom of pairing. Simplexes can be "collapsed" or "represented" by a vertex, the highest vertex. Two vertices are linked by an edge.
- Axiom of regularity.
- Axiom of extensionality. Simplexes are defined by their vertices. And the edges?
Eightfold way
- Axiom of Pairing. If x and y are sets, then there exists a set which contains x and y as elements.

- Axiom of Union. The union over the elements of a set exists.
- Axiom of Power set. For any set x, there is a set y that contains every subset of x.
- Axiom of Regularity. Every non-empty set x contains a member y such that x and y are disjoint sets.

- Axiom Schema of Specification. The subset of a set z obeying a formula ϕ(x) with one free variable x always exists.
- Axiom Schema of Replacement. The image of a set under any definable function will also fall inside a set.
