Aug 2	comment	Efficiently evaluating the Motzkin numbers @AsafKaragila: sorry typo
Aug 2	comment	A closed form for $T_N = 1 + \sum\limits_{k=0}^{N-2}{(N-1-k)T_k}$? I made a mistake sorry: See here: math.stackexchange.com/questions/177856/…

Jul 27	comment	P[random x is composite \| $2^{x-1}$ mod $x = 1$ ]? @ErickWong: Whether you can round a small number to zero depends on the application.
Jul 27	comment	P[random x is composite \| $2^{x-1}$ mod $x = 1$ ]? @ErickWong: In what way are the calculations not correct without the typo ?
Jul 27	comment	P[random x is composite \| $2^{x-1}$ mod $x = 1$ ]? I have fixed the typo and recalculated. I now get between `3.29e-306 < P_Q < 2.63e-44`, is this correct now?

Jul 27	comment	P[random x is composite \| $2^{x-1}$ mod $x = 1$ ]? If my calculations are correct than your answer is useless. The probability has been narrowed down between ~0.0 and 0.9.
