As soon as you find it and mention it in a web page, Google will return at least one result.

Fairly easy to script, but since I don't have time... I can get to [21 space 020 space 000 space 006] pretty easily (mixing it up so Google doesn't index it).

not anymore!! 
Veky  11 years ago # 
Unless you mention it in some creative noncannonical way (eg. in hexadecimal:). 
Ionut Alex. Chitu  11 years ago # 
It has 11 digits and it's <= 10000107535. 
Ben  11 years ago # 
If you put a 0 in front of 51515537 you get no results... 
Derek  11 years ago # 
its also a great way to weed out spamblogs... hitting 10 blogs with " 155253458363 [Thanks Neil!]" in it already 
imma  11 years ago # 
hehe, i have 2350813103+1 coming up with no results via random guesswork 
Vijay Dev  11 years ago # 
155253458364 is the number currently :) 
Someone  11 years ago # 
10 Digit with 9620384950 (Without any scripts, just logical guessing) 
Soumya Tilak  11 years ago # 
5210101200+1 works! 
Someone  11 years ago # 
Or 962038_4949 without the underscore 
Sidharth Dassani  11 years ago # 
Now it has 10 results. All thanks to you 
Soumya Tilak  11 years ago # 
I'm sorry.. I meant 5210101201+1 
Someone  11 years ago # 
917395729+1 is 9 Digits

Someone  11 years ago # 
Woops my maths is wrong try 9173957231

Just type as many as possible zeros (0) you will get no result 
Miguel  11 years ago # 
So far, without leading zeros, is 428532765

Miguel  11 years ago # 
Even better one – 336824481

Miguel  11 years ago # 
Right, I am done. 325670350 is the lowest one. 
Alexandre  11 years ago # 
miguel got better with his 9digit, mine was 10digit 1622441871 
Alexandre  11 years ago # 
now one smaller 9digit: 28887775+"five" looks something good to depart with "1" decrements :) until 20.000.000, something beginning with 1 seems unlikely after a few tries... 
Marcin Sochacki (Wanted)  11 years ago # 
Five digits: 0xfbfa1 ;) 
Soumya Tilak  11 years ago # 
Yep.. This works too.. 288877754 
Alexandre  11 years ago # 
actually, unitl 200.000.000. if the use of scripting brute force is discarded, one could think of statistics...
example: cluster all numbers between 200M and 288M, say, 11 clusters of 8 million numbers each, picking a 25 random sample from each cluster and then assessing from which cluster you got more than some arbitrary percentage or results counting for less than "n results".
keep these that pass the test, discard the other, beginning with the lowest one. and repeat this step, clustering in groups of 1/10th of the population so forth until you reach some countable figure. 
Soumya Tilak  11 years ago # 
How about this? 283824354 
Alexandre  11 years ago # 
203014131+"one" 
Soumya Tilak  11 years ago # 
283824354 is 9 digits long... 203014131+"one" is 10 digits long! :)

Smallest number I can find: 1611 concatenated to 12121 (9 digits) and a fairly small number.

Soumya Tilak  11 years ago # 
1611 concatenated to 12121 does return results! 
Zim  11 years ago # 
Well, it won't be any number you write here for more than a couple of hours, since Google will index it anyway :P 
noname  11 years ago # 
and what about shortest hexa? I tried e.g. 1FFD156_A and binary? what about 1010100011010101100_1 ?

The Google paradox: As soon as anyone anywhere on the web mentions that "X" (X being a word, phrase, number, or a general character string") is not to be found through Google, it is doomed to be indexed by Google in a short while*.
*Restrictions apply, in terms of whether the page is isolated, or otherwise not indexable. 
Jim Barr  11 years ago # 
Well as of 10:41 EDT on 8/21/2009, the number is now 155253458367.
Of course, this will change as soon as Google spiders this site. 
Patrick Hochstenbach  11 years ago # 
Currently it's 2 * 10^125

Jessica  11 years ago # 
"155253458363" already returns 201 results. 
Tim  11 years ago # 
Well here's the approach I'd take.
1. Choose a range of numbers, e.g. 200 000 000300 000 000. 2. Get the number of results for a sample of numbers in that range. 3. Use that to work out the probability density function. 4. Work out the liklihood that there is at least one number in that range that has no results (assuming a certain distribution, e.g. normal). 5. If the probability is e.g. >50%, choose a lower range (100m200m) and repeat. 6. Otherwise reduce the size of the range and repeat. 7. At some reasonable point, do an exhastive search until you find a result.
Except I expect google will block the searches for being botlike. 
Patrick Hochstenbach  11 years ago # 
The 9 digit number: 172 310 169 gives currently no result. Algorithm: search private ip numbers. Maybe in the 10.0.0.0 – 10.255.255.255 there are smaller numbers.
