# [−][src]Constant curve25519_dalek::constants::EIGHT_TORSION

pub const EIGHT_TORSION: [EdwardsPoint; 8]

The 8-torsion subgroup $$\mathcal E [8]$$.

In the case of Curve25519, it is cyclic; the $$i$$-th element of the array is $$[i]P$$, where $$P$$ is a point of order $$8$$ generating $$\mathcal E[8]$$.

Thus $$\mathcal E[8]$$ is the points indexed by 0,2,4,6, and $$\mathcal E[2]$$ is the points indexed by 0,4.
