    The AKS primality test runs in Õ((log n) 12) (improved to Õ((log n) 7.5) [11] in the published revision of their paper), which can be further reduced to Õ((log n) 6) if the Sophie Germain conjecture is true. [12] Subsequently, Lenstra and Pomerance presented a version of the test which runs in time Õ((log n) 6) unconditionally. [13]

If A precedes B in that frame, then A precedes B in all frames ...
