I have a list of items, that all need to be linked.
To determine the count for 4 linked items (in terms of established links)
you start at 3
3 + 2 + 1 which yields 6
Every preceding integer value.
Another example To get the link count for 5 items you do
4+3+2+1 yields 10
Is there a term for this? It is similar to factorials in the sense that every preceding integer value is used, but different in that the operator is addition in stead of multiplication.
Thanks in advance.
