If you were to scramble a 3x3 with only R, U and F moves, and were only allowed to use R, U and F moves to solve it, what would be the maximum amount of moves that an optimal solution would take?
What is God's number for a 3-gen scramble?

Idk how to find God's number but using only RUF moves that would make 3 edges and 1 corner Unable to move. So the equation for possible combinations is:
(9! × 2⁹ × 7! × 3⁷) ÷ 12
= 9,988,315,545,600
(9! × 2⁹ × 7! × 3⁷) ÷ 12
= 9,988,315,545,600

It's either 21 or 22. (See Lower bound for the diameter of the 3-gen subgroup <U,F,R>. Specifically, the posts by @Bruce MacKenzie and @rokicki.)
On Jaap's Cube Subgroups page, U, R, F = (7!*3^7/3) * (9!*2^9/2) / 2 = 170 659 735 142 400.

The links work for me now when I make it secure,
This is the link posted in the forum post which points to RUF Group Enumeration, which does not work yo.

I don't know what the problem is. If you want you can google "Domain of the Cube Forum" for a link to the site. Then, search for RUF group. There's a lot of neat stuff on the forum.
