It sounds like you’re asking about a number that was discovered in the 2000s. To give a precise answer, I need to clarify what exactly you’re looking for since many notable numbers or mathematical discoveries were identified in that decade (for example, specific Dedekind numbers in higher dimensions, large named integers related to Ramsey theory, or other mathematical constants discussed in fast-changing research). If you can share a bit more context, I can narrow down the exact item. For instance:
- Are you asking about a specific named large number (like a particular Dedekind number D(n) or another combinatorial bound) that was computed in the 2000s?
- Do you mean a widely publicized discovery or a particular number associated with a problem in Ramsey theory, combinatorics, or number theory?
- Is there a domain you have in mind (pure math, computer science, or a related field)?
Without additional context, here are two examples of notable “numbers discovered or determined” in the 2000s:
- D(9), the ninth Dedekind number, which relates to the number of monotone Boolean functions in nine dimensions, was determined after extensive computational effort in the 2010s, building on earlier work that extended the sequence from lower dimensions.
- Large finite numbers arising in Ramsey theory and combinatorics (e.g., bounds used in finite form proofs) were refined or established by researchers in the 2000s, sometimes being presented as upper bounds or specific extremal values.
If you can specify the field or provide any partial phrase, the answer can be made precise.
