Project description
Factorial Sum
Efficient computation of factorial sums using a novel recursive identity discovered by Abdelkrim Meziani.
Installation
pip install factorial-sum
Usage
from factorial_sum import factorial_sum
print(factorial_sum(5)) # Output: 153
Features
- Implements the identity S(n) = n² * (n-2)! + S(n-3)
- Faster than naive summation for large n
- Includes caching for performance
- Fully tested with pytest
