This number comes up in many discussions among certain professional circles (e.g., programmers). We are not sure why but we have our best analysts working to find out ;-)

Trivia

The great pyramids in Egypt have moved 4 kilometers with the earth's crust since they were built.

Trivia

2005

Year when D|ONE was established.

D|ONE

1729

On top of being the famous Hardy-Ramanujan number, and being a sphenic number, 1729 is also the third Carmichael number, after 561 and 1105. A Carmichael number is an integer n where bn-1 = 1 (mod n) for all b that are prime relative to n. All prime numbers have the Carmichael property.

Scientific

0.000154

Probability to get a royal flush in Texas hold 'em Poker.

Trivia

1729

Besides being the Hardy-Ramanujan number, 1729 is also a sphenic number because it is the product of three different primes (7*13*19).

Scientific

10

Number of clients representing 80% of D|ONE revenues.

D|ONE

9'721'368

The largest decimal number where you can eliminate any digit, and the number formed by the remaining digits are divisible by the eliminated digit.

Interesting but useless info (IBUI)

250

In Mandarin the number 250 (Er Bai Wu) means "moron". Nobody would accept a price or a salary at 250. Explanations about the origin of this expression differ, but a good interpretation seems "on a scale of 1000 you are 250".

Trivia

D|ONE

520

If you re-arrange things just a little bit, fate may change a lot: Swapping 2 and 5 (see 250) means a significant upgrade: In Mandarin Chinese the number 520 means, "I love you". To make an extra you may also say "520 1314": I love you forever... "13" meaning "this life", "14" meaning "until death" (or "until next life? according to religious preferences).

Trivia

1729

The Hardy-Ramanujan number. The British mathematician G. H. Hardy told this story about the Indian mathematician Srinivasa Ramanujan: "I remember once going to see him when he was ill at Putney. 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." This anecdote gave this number its name.


    9^3 + 10^3 = 1729
    1^3 + 12^3 = 1729

Scientific

Number of uninteresting natural numbers: If there were uninteresting numbers, there would be a smallest uninteresting number - but the smallest uninteresting number is itself interesting by being so, producing a contradiction.

Trivia

4444

Pragmatic as the Chinese are, if you take the the "4" (see 4) issue head-on you may turn it into a blessing: 4 times 4 i.e. 4444 means: may you be 4 times lucky in all four seasons.

Number 4 is considered an unlucky number in Chinese, Korean, and Japanese cultures because it is nearly homophonous to the word "death". In order not to take unnecessary risks, in most hotels in Hong Kong or Mainland China there is no fourth floor to choose in elevators (caring also about superstitious Westerners, the 13th floor is usually skipped as well).

Trivia
