WebIt is quite beautiful. A search for Pascal's triangle mod 2 will turn up examples. You can use Legendre's formula to find the power of $2$ dividing each factorial. From that, you can show that rows $2^n$ of Pascal's triangle consist of $1$, all even numbers, and the final $1$ because the numerator is $ (2^n)!$ and it will have a factor $2^n ...
