Re: ...nor a product of primes >/= f and F

I did not finish this question off [at least in a coherent fashion]earlier
this evening...

I think the question should be:

When does(n*O)+/-f,+/-F [where "O" is 12, "f" is 5, and "F" is 7] result in
two numbers that are neither prime nor a product of primes >/= f and F?

linear mapping, the only significant MOS which does *not* have a number of
elements which is prime is that with 12.
