Question: Are there more permutations than combinations for a series of 4digit numbers with the integers 09? Can you illustrate calculations? 

Hi, There are always more permutations than combinations since permutations are ordered combinations. Take any combination and line them up in different ways and we have different permutations. In your example there are 10C4 = 210 combinations of size 4 but 4! = 24 times as many permutations. Penny
