Theorem stoweidlem40

Description: This lemma proves that q_n is in the subalgebra, as in the proof of Lemma 1 in BrosowskiDeutsh p. 90. Q is used to represent q_n in the paper, N is used to represent n in the paper, and M is used to represent k^n in the paper. (Contributed by Glauco Siliprandi, 20-Apr-2017)
