SlotSequence

## represents the sequence of arguments supplied to a pure function.

##n represents the sequence of arguments supplied to a pure function, starting with the n argument.

## is used to represent sequences of arguments in pure functions of the form body& or Function[body].

## is equivalent to SlotSequence[ ] or SlotSequence[1].

##n is equivalent to SlotSequence[n]. n must be a positive integer.

A sequence of arguments supplied to a pure function is "spliced" into the body of the function wherever ## and so on appear.
