For x values see A200656.

For y values see A200657.

Definition: Secondary terms occured when existed such integer k that A200656 is divisible by k^2 and A200657 is divisible by k^3 and A200658 is divisible by k^6.

Terms free of such k are primary terms.

Secondary terms are: a(6)=a(2)*2^6, a(7)=a(3)*2^6.

A200218 is subset of this sequence.
