Pair calculates an Optimal Ate pairing.

RandomG1 returns x and g₁ˣ where x is a random, non-zero number read from r.

RandomG1 returns x and g₂ˣ where x is a random, non-zero number read from r.

Order is the number of elements in both G₁ and G₂: 36u⁴+36u³+18u³+6u+1.

G1 is an abstract cyclic group.

G2 is an abstract cyclic group.

GT is an abstract cyclic group.
