(a "binary number" in this context is a number that only contains 0s and 1s in its decimal expansion.)
1111's prime factorization is 11 * 101.
I firmly believe it is the only base 10 non-prime repunit number whose prime factorization consists of only binary numbers, making it a special binary number. I've tested this up to 11,111,111,111,111,111,111,111,111,111,111,111,111,111,111,111,111 (that's 50 digits) and all other results have given non-binary numbers. Since the odds of each repunit having this property decreases the larger it gets, this seems to be a solid conjecture.
I am not entirely sure about non-repunit binary numbers, nor am I sure about repunits in other numeral bases. I doubt this is the only base 10 binary number that has thi…Read more >
The False Giaxul is equal to 200!
...but not in HAN.
It's actually faxul in Steinhaus-Moser notation.
However, both this and the giaxul would look the same in how they were denoted, so this would be, in a way, a sort of lying number, an alternate interpretation.Read more >
On the short time that I have been on this site I have noted that the number of pages on this Wikia has decreased from almost 10,885 a few weeks ago to underneath 10,000 as of the time I am writing this. Upon going on the WaybackMachine, I noticed the number of pages had always increased though over time, so why are so many pages being removed at this time ?
Also, while I noticed there is a list of Googoligisms that covers the range of many numbers, there are at most about 2,000 numbers in total on this list, and yet there are almost 10,000 pages. This may mean there about 8,000 numbers not included on the list, so is there a truly all-inclusive list of every single page on this Wika ?
Lastly, when I first joined this site I wanted to ask a…Read more >
