Actually my first guess was set operations :)

>>> from sets import Set
>>> f2(Set('one'), Set('two'), Set('three'))
Set(['e', 't', 'o'])

f2 returns set of items that are common for at least two sets (i, j, k).
If you draw it on paper you'll get a nice shamrock leaf :)
You can also apply it to integers, which are sets of bits.
