Digit reversal

Sequences of the form

Table[FromDigits[Reverse[IntegerDigits[n, k, m]], k], {n, 0, km - 1}]

shown below appear in algorithms such as the fast Fourier transform and, with different values of k for different coordinates, in certain quasi-Monte Carlo schemes. (See pages 1073 and 1085.) Such sequences were considered by Johannes van der Corput in 1935.
