%N A083103 Second-order linear recurrence sequence with a(n) = a(n-1) + a(n-2).
%C A083103 a(0) = 1786772701928802632268715130455793, a(1) = 1059683225053915111058165141686995. 
               This is the second-order linear recurrence sequence with a(0) and 
               a(1) co- prime, that R. L. Graham in 1964 stated did not contain 
               any primes. It has not been verified. Graham made a mistake in the 
               calculation that was corrected by D. E. Knuth in 1990.
