[seqfan] A134675 = A007434 + A001065

Dear friends
I noticed that (at least for the first 1000 terms), A134675 = A007434 + 
A001065, though A134675 makes no mention of the other two.

Definitions:
A007434 : Jordan function J_2(n) (a generalization of phi(n)).  
A001065 : Sum of proper divisors (or aliquot parts) of n: sum of divisors 
of n that are less than n 
A134675 : Row sums of triangle A134674 
(where A134674 = A134673 * A000012, 
        and A134673 = A051731 + A127448 - I, I = Identity matrix, 
                and so on).

I hesitate in editing the "formula" section of A134675, as I have no idea 
WHY the addition works.

Is OEIS interested in me finding other non-cross-referenced sums?
