Integers Differing by 2 with Same Divisor Sum/Examples/33

Example of Integers Differing by 2 with Same Sigma
Let $\sigma: \Z_{>0} \to \Z_{>0}$ denote the $\sigma$ function: the sum of all the positive integer divisors of $n$.

Then:
 * $\sigma \left({33}\right) = \sigma \left({35}\right) = 48$

Proof
From Sigma of 33:
 * $\sigma \left({33}\right) = 48$

From Sigma of 35:
 * $\sigma \left({35}\right) = 48$

Hence the result.
