A large cardinal is a cardinal number that is larger than can be proven to exist in the ambient set theory, usually ZF or ZFC. Large cardinals arrange themselves naturally into a more or less linear order of size and consistency strength, and provide a convenient yardstick to measure the consistency strength of various other assertions that are unprovable from ZFC.
Set theorists often adopt the existence of certain large cardinals as axioms in the foundation of mathematics.
Here is a diagram showing the relation between these:
A general axiomatic framework for large cardinal axioms is proposed in
