Permutation -- From MathWorld
A permutation, also called an "arrangement number" or "order," is a
rearrangement of the elements of an ordered list S into a one-to-one
correspondence with S itself. The number of permutations on a set of n
elements is given by n! (n factorial; Uspensky 1937, p. 18). For example,
there are 2!==2.1==2 pe

Combination -- From MathWorld
The number of ways of picking k unordered outcomes from n possibilities.
Also known as the binomial coefficient or choice number and read "n choose
k," _nC_k=(n; k)=(n!)/(k!(n-k)!), where n! is a factorial (Uspensky 1937, p.
18). For example, there are (4; 2)==6 combinations of two elements out of

If the only thing that matters is the identity of the 6 numbers, and
the order
in which they were selected is not important, the function you want is
COMBINATIONS, not PERMUTATIONS. The function name is COMBIN.

Can any one give me the formula for doing permutations
ie. odds against picking 6 numbers, not in numerical order, from 45
numbers.
Excel's PERMUT function for =Permut(45.6) returns odds of
5,864,443,200
This seems too excessive, it's more like the odds of picking the 6
numbers
in numerical order.
