> Should not period be an integer?
You are right, I found both versions in the literature (integer in
Lothaire, word for instance in
http://www.springerlink.com/content/t59071u33573168v/ )
When hearing period without context, I think an integer is expected.
Although a word is definitely more useful in papers and you have the
integer by taking just the length of the word.
Is something like that stupid?
{{{
sage: Word('1231').period(word=True)
word: 123
sage: Word('1231').period()
3
}}}
> What do you think?
I think an alias is not necessary. There is no other period, and anyone
looking for that notion will use "period" anyway.
