Are there any plans to use this database, if it exists, for Social Numbers? Here is an example of Social Numbers for a Sequence of 4: - The sum of the proper divisors of 1,264,460 is 1,547,860 - The sum of the proper divisors of 1,547,860 is 1,727,636 - The sum of the proper divisors of 1,727,636 is 1,305,184 - The sum of the proper divisors of 1,305,184 is 1,264,460 ID: 770 · Rating: 0 · rate: / Reply Quote

I would assume that the Amicable Numbers project has a database with the sum of the proper divisors for many numbers. No, it's not even theoretically possible to save this amount of data. The project only stores found amicable pairs. Social numbers require different search algorithm. ID: 771 · Rating: 0 · rate: / Reply Quote
