Some Elementary Properties of SQ-universal Groups
... Since every subgroup H of finite index in a group G contains a normal subgroup N also of finite index in G, it easily follows that If a group G is SQ-universal then so is any finite index subgroup H of G ...

Famous quotes containing the words index and/or finite:
“Exile as a mode of genius no longer exists; in place of Joyce we have the fragments of work appearing in Index on Censorship.”
—Nadine Gordimer (b. 1923)
“Sisters define their rivalry in terms of competition for the gold cup of parental love. It is never perceived as a cup which runneth over, rather a finite vessel from which the more one sister drinks, the less is left for the others.”
—Elizabeth Fishel (20th century)
