%N A077554 Final terms of rows of A077553.
%C A077554 If there are two sets of distinct composite numbers satisfying the above 
               condition then the set with lesser product is chosen irrespective 
               of the number of prime divisors. Perhaps the ambiguity may not arise. 
               E.g. Row 6 is 4,6,9,10,15,25. This row can not be extended to get 
               the next row without bringing in another prime because every number 
               divisible by 2,3 or 5 will be a multiple of one of the previous terms. 
               Hence in row 7, prime 7 has to be brought in and then we get a new 
               set of numbers 4,6,9,10,14,15,21.
