For fixed n, a block (x,y) contains the numbers n/2y^2-n/2y + yz + x for all 0 <= z < n.

View on HN

Making sure I am parsing that correctly:

Is that

((n/2) * y^2) - ((n/2) * y) + (y * z) + x ? (For z ranging from 0 to n)

If so, alright, that makes more sense to me, thanks.

So, n * (y * (y-1)/2) + x + y * z ?

Edit: does HN have an escape character to deal with the asterisks?

Having whitespace after the asterisk or indenting the line by two or more spaces seem to be the only possibilities according to the "Formatting Options"[1]
