%N A067401 Minimal non-uniquely factorizable OR-numbrals, i.e. numbrals that are 
               not uniquely factorizable but for which all proper divisors are.
%C A067401 See A048888 for the definition of OR-numbral arithmetic.
%e A067401 15 is in A067401 since [15] = [3] * [5] = [3]^3 all divisors of [15] 
               are uniquely factorizable
