If I may add, the average abundancy index AI (only referred to as index in this video) is π²/6. Note how the abundancy index is a multiplicative function if the factors are relatively prime (just like the sigma function). So €(210)=€(10)*€(21)=18/10*32/21=576/210=96/35. Also we may instead group them not as friends but into abundancy index groups. If we call the abundancy index σ(n)/n=€(n) where each integers fall into a group based on floor(e^€(n)). Also since π²/6 is irrational and all abundancy index are rational numbers, there cannot exist an integer that has an abundancy index that is equal to the mean of all abundancy indexes π²/6.

Here's another way to count the index that I found myself but I think someone must have found it before: for each prime factor p raised to the power a, compute (p**(a+1)-1)/((p-1)*p**a) (this expression can also be written as (p**a*p-1)/(p**a*(p-1))) and multiply the results together. It shows that the index of the product of coprime numbers is the product of their indices

I randomly came across this channel on youtube as a 12 year old. 8 years later, I am hooked to all things maths, science and computing. I am currently majoring in CS. All because of you guys and other edutainment channels on youtube. Didnt realise its been so long. I hope you guys realise the amount of positive impact you have had on the lives of so many people. Love from India.

On these ten years of Numberphile, I've only been on this journey for the last four or five years, but I hope see where this channel goes over at least another decade to come as I've very much enjoyed the ride so far!! As for the last decade of Numberphile, we've seen Matt Parker lose all of his hair, while vampiric James appears not to have aged one bit. The former had a not-so-magic magic square named after him and has published at least one mathematics-themed book -- as quite a few other Numberphile contributors have as well (Simon Singh, Alex Bellos, and I believe Hannah Fry also to name just a few)

Love The Inbetweeners reference. "Oh, friend..."

Numbers with index less than 2 are called "deficient" numbers. The first few are 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21... The smallest known deficient friendly numbers are 135 and 273, with indices 144/135=16/15 and 297/273=99/91. OEIS only lists known friendly numbers up to 372, so I couldn't find more than that easily. Given that some of the numbers which we don't know if they're friendly are also deficient (like 10), 135 may not actually be the smallest deficient friendly number.

One of the things I like about this bit of maths is that it has no dependency on a specific base system to work. It's about the raw numbers (their values) not the numerals (the system used to represent them). 10 truly is special in this case purely on the basis of its factors, and not just because we primarily use a base 10 number system.
