%N A052359 First prime of A031938 (lesser of primes differing by 20) so that its 
               distance to the next 20-twin increases.
%C A052359 1. the smallest distance between 20-twins is 24 [= A052380(10)], while 
               its minimal increment is 6.
%C A052359 2. a(n)=p starts [p,p+20,p+6n+18,p+6n+38] and [20,6n-2,20] patterns of 
               primes and their difference.
%F A052359 a(n)=p is the smallest prime which starts a [p, p+20] twin followed by 
               the next [p+6n+18, p+6n+18+20] twin.
%e A052359 1. n=1, a(1)=46703 results in [46703,46723,46727,46747] or [20,4,20];
%e A052359 2. n=11 a(11)=5903 yields [5903,5923,5987,6007] or [20,64,20] with 4 
               primes in the medial gap.
