50 of them.1 is 10 greater than -9, 3 is 10 greater than -7, and so on.
That would depend on their values because 11 is greater than 10 but 9 is less than 10
45 of them.
So far, no odd perfect numbers have been found to exist. If and only if one does exist, it will be far larger than the number in the question. In fact, it has been proven concretely that if an odd perfect number exists, it is greater than 10^300, and it is conjectured that if such a number exists, it is greater than 10^500.
