Hello,
The sequence starts (giving the binary and decimal values):
1(1) -> 11(3) -> 01(1) -> 1011(11) -- this shows that leading 0's are to be
kept.
-> 111001(57) -> 110011(51) -> 010001(17) -> 111011(59)
Here it seems that the leading 0 is being discarded, we should have
10111011(187)
-> 111001(57) -> 110011(51) -> 010001(17) -> 10111011(187)
Here the leading 0 in 010001 is kept.
So it seems to me that leading 0's should be kept, and the sequence should
start
1, 3, 1, 11, 57, 51, 17, 187, 953, 947, 913, 827, 313, 2867, 14609, ...
Always discarding leading 0's leads to a loop
1, 3, 1, 3, 1, 3, 1, 3, ...
