%N A067482 Powers of 4 with initial digit 4.
%C A067482 Appearances to the contary, this sequence is not recursive with a geometric 
               progression factor of 1024. Examples of a(n+1)/a(n) which are not 
               1024 are a(10)/a(9) = a(20)/a(19) = a(30)/a(29) = a(57)/a(56) = a(67)/
               a(66) = 2^106 or a(39)/a(38) = a(48)/a(47)= a(86)/a(85) = 2^116.
