Features & Capabilities

Combinatorics Mathematics is a powerful Chrome extension designed for calculating and enumerating all possible permutations, combinations, and anagrams of letters and words. Ideal for students, educators, and enthusiasts, it supports a variety of combinatorial algorithms including k-permutations and combinations with repetitions.

Key features include displaying results with professionally formatted mathematical symbols using TeX/LaTeX, allowing for clear and precise presentation of computations. The extension supports Unicode characters, enabling calculations with letters from non-Latin alphabets and even emoticons. Users can easily share their calculation results by saving to a file or sending via email. Additionally, the extension offers in-app feedback options and is available in multiple languages including English, Dutch, Portuguese, and Spanish.

User Reviews

Users praise the app as beginner-friendly and helpful for learning and solving permutation and combination problems, with generally positive overall sentiment. However, recurring issues include slow performance and freezes, incomplete result displays, missing features (copy/export and search), and pricing/purchase problems that hinder access to paid features.
Pros
  • Beginner-friendly and easy to use for learning permutation and combination
  • Very helpful for solving combinatorics problems and getting the needed results
  • Generally well-regarded with positive, enthusiastic feedback (best/great/super app)
  • Feels like the app delivers what users want and provides helpful tips
Cons
  • Slow performance and occasional freezing when handling larger inputs (e.g., n=38, k=6)
  • Incomplete/limited display of results, with only a few combinations shown instead of all possibilities
  • Missing essential features like copying all results and a quick search to jump to sections
  • Pricing and purchase issues including regional restrictions and purchases not functioning properly
