Neil,

To avoid confusion, we need then to extended the definition of the
'mult' keyword given at http://oeis.org/eishelp2.html#RK
with
"mn in the the sequence if m,n are in the sequence and g.c.d.(m,n)=1"

or maybe introduce a new keyword like "mult2" (I'm still not sure if
it is a good idea to have two distinct definitions for the same
keyword).

Regards,
Max
