A095301 lists integers that have a smaller friend, that is, there exists a smaller integer with same abundancy, sigma(x)/x. In A095301 there are terms with a difference of 2, motivating this sequence.

Examples

			5850 is in the sequence because 5850 and 5852, that differ by 2, are both in A095301. That is, for both X=5850 and Y=5852, there exists 2 smaller z (x and y) such that sigma(z)/z = sigma(Z)/Z: 300 and 1254.
