%N A018844 Arises from generalized Lucas-Lehmer test for primality.
%C A018844 Apparently this was suggested by an article by R. M. Robinson.
%C A018844 Starting values for Lucas-Lehmer test that result in a zero term (mod 
               Mersenne prime Mp) after P-1 steps. - Jason Follas (jfollas_mersenne(AT)hotmail.com),

%F A018844 Union of sequences a_1=4, a_2=52, a_{n}=14*a_{n-1} - a_{n-2} and b_1=10, 
               b_2=970, b_{n}=98*b_{n-1} - b_{n-2}.
%F A018844 a[1]=14 (mod Mp), a[2]=52 (mod Mp), a[n]=(14*a[n-1]-a[n-2]) (mod Mp).

%F A018844 Though originally noted as the union of two sequences, when the first 
               sequence (14*a[n-1]-a[n-2]) is evaluated modulo a Mersenne prime, 
               the terms of the second sequence (98*b[n-1]-b[n-2]) will occur naturally 
               (just not in numerical order). - Jason Follas (jfollas_mersenne(AT)hotmail.com),
