Odd Perfect Numbers
... A triperfect number is defined to be a positive integer whose factor sum is equal to three times the original number. (The next triperfect numbers are 672 and 523776. After this there are none under 100 million – I have checked this but not by hand!) However, you notice that the factor sum here now ...

... It is well known that the sum of any ten numbers of a Fibonacci sequence is divisible by 11. For example, starting with 11, 15 and proceeding to 26,41, 67, 108, 175, 283, 458, 741, the sum of these ten terms is 1925 which is divisible by 11, the quotient being 175, the seventh member of the set of t ...
