FORMULA
| Composite x satisfying sigma[x-2n]=sigma[x]-2n.
|
|
|
EXAMPLE
| To terms of A054905, where sigma[x+2n]=sigma[x]+2n replacing x+2n=y,x=y-2n, we get sigma[y]-2n=sigma[y-2n];
For several analogous sequences, the corresponding "mirror-solutions" can be easily constructed. See: e.g. A015913-A015918; A050507,
A054799, A054903-A054906; A054982-A054987; A059118;
A055009, A055458, A063500 etc.
