Visualization of Constraints for Four or More Unique Numbers

This GeoGebra example demonstrates how to randomly generate candidates, enforce a uniqueness constraint, and obtain four or more distinct numbers under given criteria. It highlights key ideas such as randomness (sampling), uniqueness filtering (Unique), the use of a length/metric (Length) to turn geometric or numeric quantities into comparable values, and inequality-based selection logic. Construction-wise, the script uses the GeoGebra commands Random and Unique to produce and filter values so duplicates are removed; Length converts relevant objects into measurable quantities; TableText outputs the resulting unique numbers as formatted table text. The interface relies on objects such as a, b, c, d, e, f, rolls, l1, g, along with text1, text2, and button1 to present results and trigger updates interactively. Suitable for secondary school students and introductory teaching on data handling, probability/statistics, and mathematically grounded constraints.
