There are 7 digits total. The first 4 are locked in at 2021 So there are 74 = 3 digits left The last three numbers are 178 in any order and there are 3! = 3*2*1 = 6 ways to order them So there are 1*6 = 6 different phone numbers.

There are 6 teams to choose for the first slot (say the "home" slot) and 61 = 5 teams to choose for the second ("away/visitor") slot So there are 6*5 = 30 different ways to do this.

If it's all being played on one field, then order doesn't matter, so you would divide by 2 to avoid the double counting.
