Can't Touch This (A Study on Untouchable Numbers)

Untouchable numbers are numbers that cannot be written as the sum of the proper divisors of a number. For example, 8 is not untouchable because the proper divisors of 10 are 1,2, and 5 and 1 + 2 + 5 = 8. Very little is known about untouchable numbers so we will discuss certain aspects of these numbers.
