    I think that OEIS should have some sequences of A_{m,n} for small m,n.
    For example, 2<=m<=6 and 2<=n<=8
    The cases of m=n, OEIS have already for m=2,3,4

    Once I found A_{4,8} as follows

    (174547933583278080, 175583058467389440, 176359402130472960,18619308852953088
0, 180908187407646720, 181981030624296960, 182785663036784640, 192977673594961920)

    I wonder if it is the smallest one
    Could anyone compute more terms of A_{2,4} or A_{4,2} or A_{6,2} or A_{6,3}
or A_{4,8}?

    The definition of A_{m,n} is the following

    Sigma(x_i)=Sum_{1<=k<=n}  m/n*x_k , 1<=i<=n
