Wait, THAT easy ?

Now I realized that f60(64) is even closer than f60(61). I was like sitting and trying to compute the number to notations with smaller numbers used in them.

In this case, I was doing the much harder way than I could do. I just had the solution right in front of my eyes and I never saw it (And I wear glasses whut).

Thank you for help.
