In my grand ignorance I would state that graphene has a honeycomb lattice. Some tend to agree with me and some others do not. I'm curious to know what members of the SE community think is the right answer here?
My argument: The Bravais lattice of graphene is clearly not honeycomb, however a lattice does not have to be Bravais, so I see nothing wrong with saying "honeycomb lattice". I understand conventionally when one talks about lattices it is often assumed we are talking about a Bravais lattice, but this is convention and not definition.
