%N A094392 Antidiagonals of the tables formed from b(m,2,n,n), which is defined 
               in the reference.
%C A094392 This sequence can be used to help find an extension for A006209.
%D A094392 B.-S. Du, A simple method which generates infinitely many congruence 
               indentities, Fib. Quart., 27 (1989), 116-124.
%F A094392 For i=2 and k >= 1 b(k+2, 2, n, n)=b(k, 2, 1, n) + b(k+1, 2, n, n). The 
               remaining portion for the recurrence is defined in the reference.
%e A094392 E.g. for m = 5 and n = 2, b(5,2,2,2)= b(3,2,1,2) + b(4,2,2,2)= 2 because 
               of the definition in the reference.
