%N A123506 Sequence generated from the second nontrivial zero of the Riemann zeta 
               function.
%C A123506 A123054 performs an analogous set of operations using the first nontrivial 
               zero. A123507 records the lengths of runs in A123506.
%D A123506 John Derbyshire, Prime Obsession, Bernhard Riemann and the Greatest Unsolved 
               Problem in Mathematics, Plume - a Penguin Group, NY, 2003, pgs. 198-9.
%F A123506 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 deg., a(n) = 1. If 
               not, then a(n) = 0.
%e A123506 a(7) = 1 since (1/7)^z = (.37796447..., Angle 176.201...) and the argument 
               is between 0 and 180 deg.
