The number 1729 is known as the Hardy–Ramanujan number due to a famous anecdote involving mathematicians G. H. Hardy and Srinivasa Ramanujan.
Notes on verification
Confirmed by Wikipedia, MathWorld, OEIS, and arXiv sources, all tracing back to Hardy's own 1921 written account of the anecdote. [tier=gold indep_score=0.867 clusters=3 claim_tier=notable]
