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^(th) argument.
Details
- ## 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.
Examples

## represents the complete sequence of arguments supplied to the pure function:
Start with the second argument:
Scope (2)
## is short for ##1, all arguments of the function:
##2 stands for all arguments starting with the second:
Applications (2)
Programmatically insert a list of iterators into a Table :
Numerically integrate over 1000 variables:
Properties & Relations (2)
The raw object corresponding to ## is a Sequence :
#n stands for a single argument:
