Features & Capabilities

Combinatorics: Mathematics helps students, educators, and anyone studying discrete mathematics calculate and generate permutations, combinations, variations, and anagrams. Enter elements, choose how many to select, and control whether repetition is allowed.

The app displays the relevant formula, total number of possible results, and a preview of generated items. It supports anagrams with repeated letters, customizable separators, text file exports, and sharing with other apps. For large result sets, it estimates storage and generation time while showing live progress.

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
