cosetRepsGx :: Ord k => [Permutation k] -> k -> Map k (Permutation k) Source #

schreierGeneratorsGx :: Ord a => (a, Map a (Permutation a)) -> [Permutation a] -> [Permutation a] Source #

sift :: Ord k => [(k, Map k (Permutation k))] -> Permutation k -> Maybe (Permutation k) Source #

findBase :: Ord a => [Permutation a] -> a Source #

sgs :: (Ord a, Show a) => [Permutation a] -> [Permutation a] Source #

Given generators for a permutation group, return a strong generating set. The result is calculated using Schreier-Sims algorithm, and is relative to the base implied by the Ord instance

bsgs :: Ord a => [Permutation a] -> [(a, Map a (Permutation a))] Source #

bsgs' :: Ord a => [a] -> [Permutation a] -> [(a, Map a (Permutation a))] Source #

isMemberBSGS :: Ord k => [(k, Map k (Permutation k))] -> Permutation k -> Bool Source #

isMember :: (Ord t, Show t) => [Permutation t] -> Permutation t -> Bool Source #

Given generators for a group, determine whether a permutation is a member of the group, using Schreier-Sims algorithm

elts :: (Ord t, Show t) => [Permutation t] -> [Permutation t] Source #

Given generators for a group, return a (sorted) list of all elements of the group, using Schreier-Sims algorithm

order :: (Ord t, Show t) => [Permutation t] -> Integer Source #

Given generators for a group, return the order of the group (the number of elements), using Schreier-Sims algorithm
