In the case of "With Repetition", if the same character is entered multiple times, it will be counted as one.

You can enter up to 10 characters or words, but if the total number of combinations is too large, an error will occur.

The calculation results are displayed as a list of the total number of combinations and the combinations.

By changing Separator, you can choose the character separator within each combination from "Space", "No spaces", or "Comma delimited".

When "Display side by side" is selected, the combinations are displayed side by side, and when "View in tabular format" is selected, they are displayed vertically in a table format.
