f(x)=51 when x=17

f(x)=20 when x=18

The values for f(x) are the differences between the total combinations which result in a sum of x between "4d6 sans lowest" and "3d6".

But wait, you might ask, how did I derive this information if this thread is asking for "how many combinations are there for a sum of x for 4d6 sans lowest"? Aren't I missing the "4d6 sans lowest" data? Isn't that the point of this thread? How could I be using it here if I don't know it?

Many months ago--possibly a year--I wrote all the combinations for it out by hand. I also did so for "5d6 sans the two lowest values". I don't want to have to do that again for any other calculation I might want to do. That is why I am seeking a formula to assist me.

Thanks and good luck.
