It is the first number that can be expressed as sum of cube of 2 different set of 2 numbers
12^+1^3=1728+1=1729
9^3+10^=729+1000=1729

I have no idea except 1729 = 1000+729 = 10^3 + 9^3 = 19 x 91 = 19 x13x7. So it is a bit interesting since two of its factors are 7 and 13. Also, 29-17= 12 and 12^3 = 1728, and 10^3+9^3 =12^3 +1^3. He liked number theory.

1 is the fact you are first as in being #1. 7 is the old lucky number to gamble on. 2 is how many it takes to tango, and 9 is what you get when you add 2 that are getting lucky (7) and nine is the outcome of the addition.

It was the number of the cab used by Hardy when he came to visit Ramanujan, and became a topic of conversation between the two.
