You can get the effect you want by using 'srange' (which returns a list of the latter instead of the former): sage: [radical(k) for k in srange(1,31)] [1, 2, 3, 2, ... 3, 14, 29, 30] (there's also an 'xsrange' (or 'sxrange'). I don't know that there is a good way to "fix" this issue. HTH Justin -- Justin C.
