http://numbersapi.com/1729/math "1729 is a plain old number."

Can't recognize Hardy-Ramanujan number?

Also the smallest perfect number: http://numbersapi.com/6/math "6 is the smallest number of distinct isosceles right triangles that will tile an isosceles right triangle."

Ha, good catch. http://numbersapi.com/1729 (the trivia version) gives the Ramanujan fact, while we have multiple math facts for 6 (refresh a few times to get "smallest perfect number").

We're still working to build our database of facts. Feel free to send suggestions to numbersapi at google mail, and we may add a feature for user-submitted facts.

See http://numbersapi.com/1729:

> 1729 is the smallest number representable in two different ways as a sum of two positive cubes, as Ramanujan stated on the spot.

It looks like they've fixed the one for 1729.

perhaps it is a pun on Hardy, who thought it was an uninteresting number?
