I think you've doubled up on your number of combinations, I had to use a calculator to do it for me (then I learned the math to better understand it) but 5 combinations of 7 is only 21 so it's even worse. Xanathar's has expanded it out to 9 cantrips for a total of 126 combinations.
Probably. I decided to calculate how many combination of 2 'leftovers' you could end up with so I just went 7 times 6. I was sure there was a better math for that but I didn't look into it that hard.
Pretty great cantrips, though.
That's not the problem though.
