EXAMPLE
In binary, sqrt(2) is read as 1.0110101000001001111001... The 1st, 4th, 6th and 8th digits after the radix are 0's, so the first four terms are 1, 4, 6 and 8.
PROG
(PARI) default(realprecision, 150); x=sqrt(2); for(n=1, 150, if(!(floor(x*2^n)%2), print1(n, ", ")))
(PARI) Vec(select(x->(x==0), binary(sqrt(2))[2], 1)) \\ Michel Marcus, Oct 29 2018
