%N A075483 Number of iteration that first becomes smaller than the initial value 
               if Collatz-function (A006370) is iterated, starting with numbers 
               of form 64n+63.
%C A075483 1stSubmergeLengths[=A074473] with initial values belonging to other residue 
               classes modulo 64 are either listed in A075476-A075483 or can be 
               easily determined. For 64k+2s the first sink below initial value 
               is at 2nd iterate; for 64k+4s+1 the first submerge below initial 
               value comes at 4th term of iteration list; finally if initial value 
               is of 64k+4s+3 form or moreover initial value = 64k+r,r = 3,11,19,
               23,35,43,51,55 then for all k first sink emerges at the 7,9,7,9,7,
               9,7,9-th iterates respectively.
%F A075483 a(n)=A074473[64n+63]
%e A075483 n=8: 64n+63=575, the list= the 17th term 410 < 575=initial value, so 
               a(8)=17.
