classclass Group a => Cyclic a where

A Group G is Cyclic if there exists an element x of G such that for all y in G, there exists an n, such that

y = pow x n

Instances6Cyclic

valuegenerated :: Cyclic a => [a]

Generate all elements of a Cyclic group using its generator.

Note: Fuses, does not terminate even for finite groups.

valuegenerated' :: (Eq a, Cyclic a) => [a]

Lazily generate all elements of a Cyclic group using its generator.

Note: Fuses, terminates if the underlying group is finite.
