 OFFSET 0,1 LINKS FORMULA a(0)=6; for n>0 a(n)=2^(2^n)+2. a(n) = A063486(n)-3 for n>0. - R. J. Mathar, Apr 22 2007 EXAMPLE Continued fraction expansion of 1/2^(2^5)+1/2^(2^6)+1/2^(2^7)+...is [0, 4294967295, 4294967298, 4294967296, 4294967296,... ] where the maximum element is 4294967298, hence a(5)=4294967298 CROSSREFS Cf. A007400 for case n=0.
