Mistake

 * In Pascal's Triangle, each number is the sum of either of the diagonals starting immediately above it, and taking the long way to the edge: for example, $35 = 15 + 10 + 6 + 3 + 1$.

It is not necessary for the route to the edge to be the long way. The short way also works:
 * $35 = 20 + 10 + 4 + 1$
