%N A113028 a(n) is the largest integer whose base n digits are all different that 
               is divisible by each of its individual digits.
%C A113028 Note that this definition precludes the digit 0 appearing anywhere in 
               the base n representation of the number.
%D A113028 "Enigma 1343: Digital Dividend", New Scientist, Jun 04 2005, p. 28.
%e A113028 a(2) = 1 trivially because that is the only number in base 2 that does 
               not contain 0.
%e A113028 a(4) = 54 because in base 4, 54 is 312_4. There is only one number containing 
               different digits and no zeros higher than that, namely 321_4, but 
               321_4 is not divisible by 2.
