This is actually a follow-up of this previous question:
[How many vectors can be "close to mutual orthogonal like 80 degrees" in a high dimensional space?](https://math.stackexchange.com/questions/2546575/how-many-vectors-can-be-close-to-mutual-orthogonal-like-80-degrees-in-a-high-d?noredirect=1#comment5257468_2546575)

To be specific: "almost opposite" means: e.g., two unit vectors, the inner product of them is close to -1, like [-0.9 ~ -1].

My limited intuition tells me that we cannot find huge number of such vectors. Because if A is opposite to B, and B is opposite to C, then A must be C 

(This deduction does not hold true for orthogonal: A orthogonal to B and B orthogonal to C. A does not have to be C). 

Note we talk about **high-dimensional, e.g., 100-by-1** vectors.
Pls share your wisdom.
Thanks
