Let G be a group and H < G such that [ G: H] < ∞. There exists a subgroup N G such that [ G: N] < ∞. I have to show this fact (that according to my book is due to Poincaré), but I think that the statement, written in this way, is trivial: for every group G, I can take N = G, in fact G G and [ G: G] = 1.Summary. Raymond Poincaré remained president of the Republic for the duration of the war.

$\begingroup$ The Poincare recurrence theorem doesn't have much meaning in classical mechanics, either, and it gets completely eliminated by quantum mechanics. For one thing it requires a constant phase space and for perfect recurrence that space would have to be both finite dimensional and discrete (classical mechanics doesn't provide that).POINCARé, JULES HENRI.
