 Oct 12 comment How can I compute angles & lengths of the following tiling shape right :) but beside knowing angles should add up to 120 degrees or 360 degrees, I can't figure out what exactly is the portion each angle contributes... Oct 12 comment How can I compute angles & lengths of the following tiling shape I don't think you can freely change other lengths or angles. I can't prove it, but I got a hunch that changing any property of the shape freely, will break it's tiling ability, or it's symmetry. am I wrong here?

Apr 16 awarded Student Apr 16 comment How to compute the asymptotic growth of $\binom{n}{\log n}$? i'm not familiar with gamma function. i need this for proving running time complexity for an algorithm. so, i need something comparable with polynomials, poly-logarithms, or super-polynomials/exponential functions.
