Problem Statement
翻译中…
Let us write a positive integer on each face of a cube. How many ways are there to do this so that the sum of the six numbers written is $S$?
翻译中…
Here, two ways to write numbers are not distinguished when they only differ by rotation. (Numbers have no direction.)
翻译中…
The count can be enormous, so find it modulo $998244353$.
