This deals with an aspect of the Josephus problem.

Contribution from Paul Curtz, May 30 2011: (Start)

For comparison with A000265, one can arrange the sequence in blocks of length (and with row sum) 2^k, like

1;

1;

1,  3;

1,  5, 3,  7;

1,  9, 5, 13, 3,  7, 11, 15;

1, 17, 9, 25, 5, 13, 21, 29, 3, 7, 11, 15, 19, 23, 27, 31;

or

1,  1,

1,  3,

1,  5, 3, 7,

1,  9, 5, 13, 3,  7, 11, 15,

The even numbers of A181733 are essentially A152423:

2,

2,4,

2,4,6,8,

2,4,6,8,10,12,14,16,

2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32.
