In most esports titles a pool of maps is defined before a match begins. Teams take turns vetoing maps until the required number of maps for the series remains.
The combinatorial problem is to count how many distinct orders the remaining maps can appear once the veto phase is over. Because the vetoes simply remove maps, the order of the leftover maps is a permutation of the remaining set.
If M is the total map pool and each team vetoes V maps, the number of possible map orders is given by the factorial of the remaining maps.
