I thought I'd try the same thing with squares...
Here's what I computed by hand (which means it may contain errors)...
0, 10, 24, 3, 6, 1, 8, 14, 4, 9, 16, 12, 15, 21, 25, 2, 5, 26, 11, 52, 20,
41,
38, 44, 68, 49, 18, 28, 81, 34, 29, 7, 48, 19, 27, 13, 36, 31,
If we start with 1 instead of 0...
1, 6, 3, 16, 9, 4, 14, 8, 29, 5, 2, 11, 26, 10,
...next term depends on whether we allow 0, or restrict terms to positive
integers (in which case it's 24).
I'm guessing it will be a little harder to prove whether or not these
contain every positive integer.
