Can zigzag carbon nanotubes be expressed as a mathematical vector?

In summary, the conditions for a zigzag carbon nanotube can be expressed as "either n=0 or m=0, but not both." Alternatively, n=0 and m is not equal to 0 can also be used.

Homework Statement


I'm trying to express the conditions for a zigzag carbon nanotube in a mathematical vector.


Homework Equations



B = na1 + ma2

The Attempt at a Solution



I want to say "either a=0 or b=0", but must I also say that it can't be a=b=0 or is that already excluded in the statement? I'm not sure of the mathematical logic at work.
Thanks in advance
P.S B, a1 and a2 are vectors, but I couldn't find the bold button.

You could say "either ##n=0## or ##m=0## but not both." Alternatively, since ##\mathbf{a}_1## and ##\mathbf{a}_2## are identical graphene unit cell vectors, they're interchangeable, so you could just say "##n=0## and ##m \neq 0##," which is equivalent to the first statement.
