%N A059865 Product(p(i)-6), i=4,5...n.
%C A059865 Arises in Hardy-Littlewood prime k-tuplet conjectural formulas. Also 
               the sequence gives the exact numbers of X42424Y difference-pattern 
               in dRRS[m], where m=modulus=A002110(n). See A049296 (=dRRS[210]=list 
               of first differences of reduced residue system modulo 210=4th primorial). 
               A pattern X42424Y corresponds to a residue-sextuple or it is their 
               difference-quintuple, X,Y>4. Analogous pattern for primes is in A022008.
