I think we may need a better statement of your question, as it is it
is incomprehensible to me at least.

I agree with you cap'n black,
what I want to know is the definition of "pairwise" and even more important is "relatively prime" how can something be relatively prime? If it's prime it's prime, if it's not it's not.

Two numbers are relativly prime if their gcd is 1.

5. Perhaps he is shy an he means,

$\gcd(a,b)=1\leftarrow \rightarrow \gcd(a^2,b^2)=1$
