A130879 An anti-diagonal triangular sequence based on sums of fractal self-similar level count totals of the sort:Sum[k^(2^n), {n, 0, m}]. 0

COMMENTS

I used the "Reverse" in this anti-diagonal transform so that the first column is the low numbers of the fractal states themselves.

The row sum is given by:

Table[Apply[Plus, Table[a[[n, l - n]], {n, 1, l - 1}]], {l, 1, Dimensions[a][[1]] + 1}]

0,2,9,38,396,72780,4338153001,18448597102531915732...

This sort of statistics is basic to things like Zipf word frequency and other fractal dimension determinations.

FORMULA

a(m,k)=Sum[k^(2^n), {n, 0, m}] T(n,m)=anti-diagonal_transform[a(m,k)] ( see the Mathematica code below)

MATHEMATICA

f[m_, k_] := Sum[k^(2^n), {n, 0, m}]; a = Table[f[m, k], {k, 2, 12}, {m, 0, 10}]; c = Table[Reverse[Table[a[[n, l - n]], {n, 1, l - 1}]], {l, 1, Dimensions[a][[1]] + 1}]; Flatten[c]
