%N A101336 Alternating addition and subtraction of the residues of the primes less 
               than the number.
%C A101336 The amplitude and periodicity of fluctuations increase... for example 
               a(813) through a(836) are all positive and a(914) through a(937) 
               all are positive except for a(922).
%e A101336 a(10) = -4 because 10 (mod 2) - 10 (mod 3) + 10 (mod 5) - 10 (mod 7) 
               = 0-1+0-3
%Y A101336 Cf. A024934.
