A: I'm stronger than person B, and all the other people here combined.
A: I'm stronger than person B and all the other people here combined.
Does the comma convey a slightly different meaning?
The different meaning is that Person B is in the group of people combined in the second sentence, while Person B is separate from the people combined in the first sentence? Meaning the power of Person A in the second sentence would be stronger than Person B + Everyone else combined. While Person A in the first sentence would be stronger than Person B, and also stronger than everyone else combined. I'm not sure if my thinking makes much sense, but I hope you understand.
