Explore unique combinations and full arrangements from four numbers. Review totals, patterns, and exportable results. Built for faster counting practice and analysis.
| Example Numbers | Unique Pairs | Unique Triples | Four Number Combinations | Ordered Arrangements |
|---|---|---|---|---|
| 1, 2, 3, 4 | 6 | 4 | 1 | 24 |
| 2, 2, 3, 4 | 4 | 3 | 1 | 12 |
| 5, 5, 5, 5 | 1 | 1 | 1 | 1 |
This calculator works with combination and permutation logic.
For four distinct numbers, unique pairs equal 4C2 = 6. Unique triples equal 4C3 = 4. One four-number combination exists because 4C4 = 1. Full ordered arrangements equal 4! = 24. When duplicate values appear, repeated outputs are removed, so the final list stays unique.
This all possible combinations of 4 numbers calculator helps you organize number sets fast. It lists unique combinations and full ordered arrangements. That makes it useful for classroom practice, puzzle work, coding tests, and basic probability review.
You enter four numbers once. The tool then creates single-value sets, pair sets, triple sets, and one four-value combination. It also builds every unique arrangement of the four inputs. The summary section shows how many results appear in each group.
Many manual methods become confusing when numbers repeat. This calculator removes duplicate outputs automatically. That means the final list stays clean and easier to verify. If you enter 2, 2, 3, and 4, repeated pairings and repeated arrangements are counted only once.
Combination logic appears in many math topics. You may need it for set theory, counting principles, sampling, and simple decision models. Ordered arrangements are also useful when position matters. Examples include lock patterns, digit studies, rank ordering, and sequence testing.
The result area appears above the form after submission. This keeps the answer easy to find. You can scan the counts, review the full lists, and then export them. CSV files help with spreadsheet work. PDF files help with printing, records, and homework sharing.
The page uses a clean white layout with minimal styling. Inputs are arranged in a responsive grid, so the calculator stays usable across screen sizes. The structure also supports fast editing. You can change one value, run the calculation again, and compare results immediately.
It generates unique single-number, pair, triple, and four-number combinations from your inputs. It also lists every unique full-length arrangement of the four numbers.
No. Standard combinations ignore order. The separate ordered arrangements section shows sequences where position matters. That gives you both views on the same input set.
Yes. The calculator accepts repeated values. It removes repeated outputs, so you only see unique combinations and unique arrangements in the final result lists.
When you choose all four values from exactly four inputs, there is only one combination. That result contains the entire set, regardless of the order of selection.
There are 24 full arrangements when all four numbers are different. This comes from 4!, which equals 4 × 3 × 2 × 1.
Yes. It is useful for counting outcomes, checking sample spaces, comparing ordered and unordered results, and understanding how repeated values affect totals.
You can export the generated results as CSV and PDF. CSV is convenient for spreadsheet tools, while PDF is better for printing and sharing.
Yes. The inputs support decimals as well as whole numbers. The calculator treats them as values and generates unique outputs from the exact entries submitted.
