What is the lowest possible value of the highest number on one of the dice faces?

Helpful. I use my original method, borrow Charlie's numbers and plug them in with Dej's suggestion about adding and subtracting, so that the largest number is 21, as per your post:

(x^16+x^17+x^18+x^19+x^20+x^21)*(x^(-15)+x^(-9)+x^(-3)+3+x^9+x^15)=

x + x^2 + x^3 + x^4 + x^5 + x^6 + x^7 + x^8 + x^9 + x^10 + x^11 + x^12 + x^13 + x^14 + x^15 + 4 x^16 + 4 x^17 + 4 x^18 + 3 x^19 + 3 x^20 + 3 x^21 + x^25 + x^26 + x^27 + x^28 + x^29 + x^30 + x^31 + x^32 + x^33 + x^34 + x^35 + x^36.

Aren't committees great?

I look forward to seeing the proof that it is minimal in due course.

It's amazing  that even though all 36 numbers can be scored, there are still, according to the expansion, apparently 3 or 4 different ways of making  each of the numbers from 17 to 21. Seems almost too good to be true...
