Permutation & Combination Calculator
Perform combinatorial calculations including permutations, combinations, circular arrangements, multiset permutations, and Stirling numbers. Supports batch processing, sequence generation, probability analysis, and interactive visualizations.
Key Features
- • Permutations and combinations (P(n,r), C(n,r))
- • Permutation & combination with repetition
- • Circular permutations and multiset arrangements
- • Stirling numbers (first & second kind)
- • Binomial coefficient calculations
- • Sequence generation (permutations & combinations)
- • Batch processing (CSV or text input)
- • Probability calculations (lottery & event scenarios)
- • Comparison of multiple calculations
- • Interactive charts (bar & pie visualizations)
- • History tracking with export (CSV, JSON, PDF)
Use Cases
- • Probability and combinatorics problems
- • Lottery and event probability analysis
- • Algorithm design and optimization
- • Cryptography and key generation
- • Academic learning and exam preparation
