comment Decomposition of a nonsquare affine matrix
@acs: I don't see a well-defined question there. If you tell me specifically which equation in the article you're comparing with which equation in my answer, and why you'd expect them to be compatible or not, and what it would mean for them to be compatible, I'll be happy to answer.

comment Decomposition of a nonsquare affine matrix
@acs: There are a whole lot of equations in that article. Which equations are you interested in, and which equations should they be compatible with, in what sense?

comment probability,calculus
This is an almost exact duplicate of math.stackexchange.com/questions/1642329/…. Please don't do that; it wastes everyone's time. If you wanted to add a sentence to the other question, there's an edit button underneath the question for that.

comment Find number of rectangles
No. I doubt much can be said about it in this generality -- the result depends on all the details of $X$.

comment If the $\Pr($hypothesis) is due only to chance, then what is the problem?
@LePressentiment: No, each has probability $1/216$, for a total of $1/36$.

You're missing a factor $1/2$ in the count in the last line.

comment Find the number of seating arrangements at a round table of three single men, two single women, and two families
@DreadfulWithMaths: There are $7!/7$ cyclically inequivalent arrangements of the $7$ men, women and family blocks. There are $11$ seats, so each of these cyclically inequivalent arrangements can be placed on the numbered seats in $11$ different ways.

comment Why doesn't Cantor's diagonalization work on integers?
@birna: Yes, it is.

comment Why doesn't Cantor's diagonalization work on integers?
@birna: It doesn't matter how you change the digit, by adding or randomly -- as long as you change each digit, you either have to stop or construct an infinite string of digits. The situation is different for reals because an infinite string of digits defines a real number, but it doesn't define an integer. So you don't have to stop for reals.
