##### Arity: monadic

##### Functionality

Like `ŒṖ`

(Partition); partition a list but return `[[]]`

for the empty list.

##### Details

The partition of `z`

is the list of all ways to divide `z`

into sublists. For example, `3R Œb`

returns `[[[1], [2], [3]], [[1], [2, 3]], [[1, 2], [3]], [[1, 2, 3]]]`
