Rotavirus has many variations. All the variations are generated from a wheel, which contains a cycle of N nodes, with an extra node connected to each one on the cycle, as shown in the picture:

All the valid rotaviruses are formed by breaking some edges from the wheel, such that every two nodes have one and only N=100one path to reach each other. When N=3, there are 16 different valid rotaviruses:

For a wheel containing a cycle of N=100 nodes, there are n different rotaviruses to generate from.

How many digits are in n expressed in base 10?

take a look at this table: https://snipboard.io/X75u9W.jpg

Macho14 · Answer

ok, so now I use the matrix tree theorem...

Macho14 · Answer

oh ok, I got the same answer after using what you gave me.

_A100​=(1+sqrt(5)/2)^200 + (1-sqrt(5)/2)^200 -2 this has 42 digits

ironm4n · Answer

yup, there you go, answer checked

Macho14 · Answer

Thanks t0n3. and are you still using the same IP as me?

ironm4n · Answer

yeah lol, last night they thought it was just you in all those accounts

Macho14 · Answer

LOL I would have to be the flash to be in all of those, for someone so smart, Tso didn't use any common sense. and he mocked us I don't know if you saw that

ironm4n · Answer

oh I saw, don't worry, he just thinks we can't do this stuff because he doesn't realize how easy and simple this stuff is.
