I am an undergraduate student at the University of Maryland, College Park, where I am currently pursuing a bachelors in computer science.

I am primarily interested in web application development, real-time data analysis, "software-as-a-service" as a model of software delivery, the impact of macroeconomic fluctuations on foreign exchange markets, and improving the human condition through emerging technological innovations. I like to move fast and break things.

Wow $\phi(2^k) = p^(k-1)*(p-1)$ is exactly what I was looking for, what an amazing equality.

comment How do I compute Euler phi function efficiently for repeated prime factors?
(e,n) = (17, 323) and the ciphertext was 185 but I was trying to keep the question general so that I could learn the underlying way to quickly compute $\phi(n)$ in a variety of problems

comment Show that there is no integer n with $\phi(n)$ = 14
Thanks. I see how $n = 2^a 3^b$ but then why is $\phi(n) = 2^a 3^{b-1}$? What equality establishes that relationship?

comment Show that $\sigma(n)$ = 5 has no solution
Just to make sure I understand the sigma function, $\sigma(4)$ = 1+2+4 = 7, $\sigma(3)$ = 1+3 = 4, $\sigma(2)$ = 1+2 = 3 and $\sigma(1)$ = 1, correct? Sorry for the silly question but I just want to make sure that it includes itself... but I suppose it must since we are including 1
