Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Sequence generated from the second nontrivial zero of the Riemann zeta function.
%C A123504 performs an analogous set of operations using the first nontrivial zero. A123507 records the lengths of runs in A123506.

%F Let z = (1/2 + i*t), t = 21.022039639... (the second nontrivial Riemann zeta function zero). Perform (1/n)^z, (n = 2, 3, 4, ...) extracting the argument. If the argument is between 0 and 180 degrees, a(n) = 1. If not, then a(n) = 0.
%e a(7) = 1 since (1/7)^z = (0.37796447..., angle 176.201... degrees) and the argument is between 0 and 180 degrees.
