%N A182765 Beatty sequence for (6 + sqrt(2))/4.
%C A182765 Let u=(1+sqrt(2))/2 and v=sqrt(2). Jointly rank {ju} and {kv} as in the first comment at A182760; a(n) is the position of nu.
%F A182765 a(n) = floor(r*n), where r = (6 + sqrt(2))/4.
%F A182765 a(n) = 2*n - 1 - floor(n/7) for n < 41, but this fails for a(41) = 75 onwards. - _M. F. Hasler_, Jun 23 2016

%o A182765 (PARI) A182765(n)=n*(6+sqrt(2))\4 \\ Requires sufficient realprecision (but the 64-bit default is enough up to n = 10^38). - _M. F. Hasler_, Jun 23 2016
