%N A093492 Define the divisor symmetry of a number n to be k if n-r and n+r have 
               the same number of divisors for r = 1 to k but not for k+1. Sequence 
               contains the divisor symmetry of n.
%C A093492 Subsidiary sequence: Indices of the first occurrence of n in this sequence.
%C A093492 Is this sequence bounded? Through n = 20000, a(432)=6 is the only value 
               greater than 4. - Frank Adams-Watters (FrankTAW(AT)Netscape.net),
