%N A068797 Minimum x such that f(x)=n, where f(x)=A068796(x) is the maximum k such 
               that k consecutive integers starting at x have distinct numbers of 
               prime factors (counted with multiplicity).
%C A068797 The number of prime factors (counted with multiplicity) of n is bigomega(n) 
               = A001222(n).
%C A068797 The known terms, except for the first, agree with A067665. Is that true 
               forever?
