In,

http://www.research.att.com/cgi-bin/access.cgi/as/njas/sequences/eisA.cgi?A
num=A069220

we have the denominators of the sequence:

sum{1<=k<=n,GCD(k,n)=1} 1/k.


But the EIS, curiously, does not have the numerators, nor does it have 
the sequence of the  above sum multiplied by n!.

I was looking at this old sci.math post of mine, which inspired the email 
to seq.fan.
