The sequence is defined by considering first m<=k, adding the difference prime(m)*k-prime(k)*m to the sequence if >=0, then considering for the same semiprime m>=k, and adding the difference also to the sequence if >=0 and if different from the previous swapped case. - R. J. Mathar, May 06 2010
EXAMPLE
a(1)=0 because prime(1)*1-prime(1)*1=2-2=0; a(2)=1 because prime(1)*2-prime(2)*1=4-3=1.
