Tau of n cubed
Rule
Each term is: The number cubed, then take the number of the divisors
Known as: Tau of n cubed
The number of divisors of n cubed.
The first 50 terms (starting from n=1) are:
1 4 4 7 4 16 4 10 7 16 4 28 4 16 16 13 4 28 4 28 16 16 4 40 7 16 10 28 4 64 4 16 16 16 16 49 4 16 16 40 4 64 4 28 28 16 4 52 7 28
Example
To get the value for n=13:
- Cube the number, giving 2197.
- Find the number's divisors, giving 1, 13, 169, 2197
- Count them, giving 4.
So the result is 4.
