Project Euler #203: Squarefree Binomial Coefficients

  • + 2 comments

    Without spoiling the challange, could somebody plz answer me how the following criterion is meant:

    "Find the sum of the distinct squarefree numbers in the first rows of Pascal's triangle."

    The question asks for the sum of distinct squarefree numbers. QUESTION: Does this mean the sum of all the numbers witch have distinct mod (10E9+7)? I mean in the binomial table with millions of large numbers, I dont see, why two distinct numbers couldnt have the same modulo 10E9+7. How to account for those numbers?
