SUMMARY
The harmonic factorial series sum, represented as ## \frac{1}{1!} + \frac{1}{2!} + \frac{1}{3!} + \frac{1}{4!} + ... ##, converges to the mathematical constant e - 1, approximately equal to 1.718. This conclusion is supported by references to calculus literature, specifically the Purcell Calculus textbook. The series is not classified as either geometric or arithmetic, which complicates its evaluation without advanced techniques.
