= Pascals Triangle =


== Construction ==

Pascals triangle is constructed via staggering numbers in rows, and making each
entry equal to the sum of the two entries above it.

For some entry `(i,j)` where `i` is the row and `j` is the column, the value
can be calculated via

`f(i,j) = f(i-1, j-1) + f(i-1,j)`

== Patterns ==

* The sum of elements in a row is twice the sum of the row proceeding it. Or in
  other words, the sum of the elements in row `n` is `2^n`.
* The sum of the square of the elements of row `n` is equal to the middle
  element of row `2n`
* For some row `n` where `n` is prime, all terms in that row except for the 1s
  are multiples of `p`
