Integers Differing by 2 with Same Divisor Sum/Examples/284

Example of Integers Differing by 2 with Same Divisor Sum
Let $\sigma_1: \Z_{>0} \to \Z_{>0}$ denote the divisor sum function.

Then:
 * $\map {\sigma_1} {284} = \map {\sigma_1} {286} = 504$

Proof
From :
 * $\map {\sigma_1} {284} = 504$

From :
 * $\map {\sigma_1} {286} = 504$

Hence the result.
