what the H?

[edit]

I'm lost already. Is H a list of words or a list of generators? Does it begin empty, or what? —Tamfang (talk) 06:13, 2 September 2012 (UTC)[reply]

H is a subgroup of G, and does not change during the course of the algorithm. H is represented by a list of words hi from X′ whose images generate the subgroup H. This list and those words do not change during the course of the algorithm. JackSchmidt (talk)
