Function exp_1420470955 

pub fn exp_1420470955<R: PrimeCharacteristicRing>(val: R) -> R

Compute the exponential x -> x^1420470955 using a custom addition chain.

This map computes the third root of x if x is a member of the field KoalaBear. This follows from the computation: 3 * 1420470955 = 2*(2^31 - 2^24) + 1 = 1 mod (p - 1).
