2. Theorem


             There are many parameter solutions of A16+ A26+ A36+ A46+ A56+ A66 = B16+ B26+ B36+ B46+ B56+ B66.



             A16+ A26+ A36+ A46+ A56+ A66 = B16+ B26+ B36+ B46+ B56+ B66.................(1)
           

Proof.           


             A1=a1a+b1b-c1
             A2=a3a+c3
             A3=a4a+c4
             A4=a1a-b2b+c2
             A5=a2a-b1b+c2
             A6=a2a+b2b+c2
             B1=a1a+b1b+c1
             B2=a3a-c3
             B3=a4a-c4
             B4=a1a-b2b-c2
             B5=a2a-b1b-c2
             B6=a2a+b2b-c2

      A16+ A26+ A36+ A46+ A56+ A66 = B16+ B26+ B36+ B46+ B56+ B66.............................(2)

      a2=ma1,a3=na1,a4=pa1,c1=qc2,c3=rc2,c4=tc2
      As for this equation (2), the factorization is done as follows.
 
      |(m,n,p,q,r,t)|<6

      (m,n,p,q,r,t)

      (3 1 -1 -2 -6  3) 240a1ac2(-19c22+b22b2+2a1b2ba+4a2a12)(21c22+b22b2+2a1b2ba+6a2a12)
      (3 1 -1 -1 -5  3) 240a1ac2(14c22+6a12a2+2b2ba1a+b22b2)(-12c22+4a12a2+2b2ba1a+b22b2)
      (3 1 -1 2  -2  3) 240a1ac2(5c22+b22b2+2a1ab2b+6a12a2)(-3c22+b22b2+2a1ab2b+4a12a2)
      (3 1 -1 3  -3  1) 240a1ac2(6c22+b22b2+2a1ab2b+6a2a12)(-4c22+b22b2+2a1ab2b+4a2a12)
      (3 2 -4 3   2  2) -240a1ac2(5c22+15a2a12+2ba1ab2+b22b2)(3c22+5a2a12-2ba1ab2-b22b2)
      (3 3 -5 3   2  2) -240a1ac2(3c22-b22b2-2a1ab2b+12a12a2)(5c22+b22b2+2a1ab2b+22a12a2)
      (3 4 -6 3   2  2) -240a1ac2(3c22+21a12a2-2b2a1ba-b22b2)(5c22+31a12a2+2b2a1ba+b22b2)
     



    Take c2=1
    
    Case 1. 4a2a12+2a1b2ba+b22b2=19.....................................(3)
    

    We can find infinitely many rational solutions of (3),then we obtain infinitely parameter solutions of (2).

    Take x=2a1a,y=b2b 

    Then (3) becomes to x2+xy+y2=19........................................(4)

    (x,y)=(3,2) is a solution of (4).

    We obtain parameter solution of (3) by using (a,b)=(3/(2a1),2/b2).
