%N A074915 Largest x such that the number of nonprimes (i.e. 1 and composites) in 
               the reduced residue set (RSS(x)) of x equals n, or 0 if there are 
               no such numbers.
%C A074915 It is conjectured that x is always bounded.
%F A074915 a(n)=Max{x; A048864(x)=n}; a(n)=0 if no such number exists [See A072023].
%e A074915 One nonprime [=1] is in RRS of {1,2,3,4,6,8,12,18,24,30}; min=1,max=30. 
               See A048597.Two nonprimes are in RRS of {5,10,14,20,42,60}; min=A072022[2], 
               max=a[2]=60 here.For entries of A072023 neither min, no max is believed 
               to exist.
