What Ono and Trebat-Leder had discovered, in other words, was that the Hardy-Ramanujan number, 1729 was known to Ramanujan as a solution to equation 6 above, expressible as the expansion of powers of ξ, given by the coefficients α, β, γ for n = 0, namely α₀ = 9, β₀ = −12, γ₀ = −10.

No, Hardy! The number 1728 is one less than the Hardy-Ramanujan number 1729 (taxicab number) Note that the values of n s (spectral index) 0.965, of the average of the Omega mesons Regge slope 0.987428571 and of the dilaton 0.989117352243, are also connected to the following two Rogers-Ramanujan … 1729 is the natural number following 1728 and preceding 1730. It is a taxicab number, and is variously known as Ramanujan's number and the Ramanujan-Hardy number, after an anecdote of the British mathematician G. H. Hardy when he visited Indian mathematician Srinivasa Ramanujan in hospital. He related their conversation: Ramanujan is said to have made this observation to Hardy who happened to be visiting him while he was recovering in a sanatorium in England, in the year 1918; on entering Ramanujan’s room, Hardy apparently said (perhaps just to start a conversation), “I came in a taxi whose number was 1729.

I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. "No", he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways." The Hardy-Ramanujan number stems from an anecdote wherein the British mathematician GH Hardy had gone to meet S Ramanujan in hospital. Hardy said that he came in a taxi having the number '1729', What Ono and Trebat-Leder had discovered, in other words, was that the Hardy-Ramanujan number, 1729 was known to Ramanujan as a solution to equation 6 above, expressible as the expansion of powers of ξ, given by the coefficients α, β, γ for n = 0, namely α₀ = 9, β₀ = −12, γ₀ = −10.

In his famous letters of 16 January 1913 and 29 February 1913 to G. H. Hardy, Ramanujan [23, pp. xxiii-xxx, 349–353] made several assertions about prime numbers, including formulas for π(x), the number of prime numbers less than or equal to x.Some of those formulas were analyzed by Hardy [3], [5, pp. 234–238] in 1937.
