| Aug 10, 2017 at 7:28 | comment | added | Felix Torssell | I took 325 as n because that is my current number of options. sorry I should have clarified. I edited the question | |

| Aug 10, 2017 at 7:16 | comment | added | Stingy | \$n\choose r\$ is equivalent to \$\frac{n!}{r!\cdot(n-r)!}\$. It doesn't count permutations. So the question how you got 5668650 still stands. | |
| Aug 10, 2017 at 5:48 | comment | added | Felix Torssell | That is correct Stingy. Each serial number has about 60 lines. 1 for each of its options. And it can't have the same option twice. | |
| Aug 10, 2017 at 5:46 | comment | added | Felix Torssell | I don't want permutations. I am interested in combinations and I don't want position specific or repetition. Formula I am using is n!/r!(n-r)! | |
| Aug 9, 2017 at 21:43 | comment | added | Stingy | Also, I am confused how you got the number \$5668650\$, could you elaborate on that please? \${350\choose 3}=7084700\$, and \${350\choose 2}=61075\$, and \$2^{350}=2.29349861599007 \cdot 10^{105}\$, so maybe I misunderstood something in your question. | |
| Aug 9, 2017 at 20:41 | comment | added | Stingy | Just to clarify: Each serial number can have an arbitrary number of options associated with it, and it's just a characteristic of the input format that a line contains just one option for a serial number? | |
