Brady's comment about a power of two being all 4s was initially intriguing, but I think it's fairly easy to see why a power of 2 greater than 2 cannot be all 4s: the previous one would be all 2s and the one before that would be all 1s, which is odd and clearly not a power of 2. Edit: I should have said (instead of "a power of 2 greater than 2") something like "a power greater than 2 of 2" or, better I think, "2ⁿ, where n > 2". I appear to have caused some confusion and debate. Sorry, everyone. @hectorbector11 put it better (I summarise): 2ⁿ = 4444…4444 ⇒ 2ⁿ⁻¹ = 2222…2222 ⇒ 2ⁿ⁻² = 1111…1111 which is odd, so not 2ⁿ for any n > 2.

I ran some code and checked what the highest n was for p^n where p is every prime below 100, and n = 1-100,000. No other p has a larger n than 2. The larger p gets, the smaller max n becomes. The sums with the highest n all seem to average around 8300 digits in length, so I suppose that around that number of digits the chance that any random combination of p and n will contain three 6's consecutively approaches 100%

9:20 Yes, you can tell from his smile. I like that earth contains such peeps

A power of 2 can never be all 4s. If it was, the previous power would be all 2s, and the previous one would be all 1s which is not even a multiple of 2, let alone a power of 2. In general, the powers of some bases may have a balanced distribution of digits (that means about as many 1s as there are 2s or 3s etc.) but the distribution is nonetheless random in the sense that some combinations are not allowed. For example, the powers of 7 will end in 01, 07, 49 and 43. That alone already eliminates many random combinations.

What about negative powers of 2, and looking for 666 in their decimal expansion after the decimal point?

Does 666 occur within the decimal part of the value of Pi? Considering Pi up to 10,000 decimal integers - yes it does. The first time occurs at decimal integers 3151-3; then at integers 4435-7 and then at integers 5403-5; and there are many more times that 666 occurs beyond the first 10,000 decimal integers.

If something so "small" as 2^⁶⁶⁶ planck times already breaks any concept of time in our universe. 2^(busy beavers n) planck times is even more absurd

I think it would be fairly simple to prove that a power of 2 can't be all 1 number. Every power of 2 is double the previous. So to get all 4s, the previous would half to be all 2s, and the one before that all 1s. Odd numbers aren't possible. Am I correct in that, or are my recreational maths not mathing?

Some say it is not 666 it is 999 since when seen in a paint the circles of the three digits are touching, so rotating around the center what is seen is a 9, not a 6; to be a six, the tips (vertex) of each 6 would be touching on a common point, but that is not the case, what are touching is the tthree circles (all three circles are tangent two by ywo), and the three circles have their centers forming an equilateral triangle.

2^x can't be all 4s because then 2^(x-2) is all 1s, but all powers of two are even for any x>0.

This all breaks with any other base
