In the title text, since groups are a concept within mathematics, it seems odd to consider mathematics as a whole forming any sort of group within itself, which I suspect is the first part of the pun. Secondly, since groups involve the commutative property, I think the last part is a pun about the order of the words algebra and geometry, as if they're commutative themselves!

: I meant to say 'abelian' groups involve the commutative property, and the meta prefix is referring to the fact that it's about the names rather than the mathematical details - i.e. commutative in metadata only.

It's a false dilemma. Complex numbers ''are'' vectors (<math>\mathbb{C}</math> is a two-dimensional <math>\mathbb{R}</math>-vector space, and more generally every field is a vector space over any subfield), but that doesn't change anything about the fact that <math>i</math> is by definition a square root of -1.
