Digit averages and cumulative sums

Density plot of the average values of the digits of for various bases .

Density plot of the iterated cumulative sums , of the digits of modulo for various bases .

3D plots of the iterated averages , , odd (and a similar definition for even) of the digits of for and for various bases . No values are displayed in the right front corner because the initial digit sequence starts at and so does not allow to form symmetric average. For increasing iteration number , the averages approach .
