Seqfans, 
     Are these sequences the same? 
  http://oeis.org/search?q=A208446|A172634 
I.e., is it true that: 
(*) The inverse binomial transform of the Franel numbers yields the 
Number of n X 3 0..2 arrays with row sums 3 and column sums n ? 
 
If the above (*) is true, does it lead to a more general formula? 
 
Thanks, 
     Paul
