I am working on a weekend project idea and was wondering if anyone on
the list could verify a math problem for me?
Here is the problem.
If one takes the characters a-z and numbers 1-9 this gives one 35
possible character options.
Now if used in a sequence of up to 3 characters.
I get a total of 6,545 possible combinations of these 35 characters.
Now if one was to use them in file folder tree style structure such as,
ad6 / 7gh / d8s
My math shows there is 46,706,638,440 possible combinations of these
35 characters in a 3 layer deep tree.
Do you get the same results or am I doing something wrong here?
Thanks your thoughts on the matter.

This is the rather quick and dirty Python code I used to get to these
results today.
import math
a = math.factorial(35)
b = math.factorial(35-3)
c = math.factorial(3)
d = a / (b*c)
'{:,}'.format(d)
#'6,545'
e = math.factorial(6545)
f = math.factorial(6545-3)
g = math.factorial(3)
h = e / (f*g)
'{:,}'.format(h)
#'46,706,638,440'
