I have been searching for an online calculator or a program which graphically shows the resulting permutations and combinations. If there are 3 objects and we need combination of any two at a time, then there are going to be 3 combinations in total. Is there a calculator or program which when given three values such as A, B, and C, then it shows combinations as AB, AC, BC? Please let me know if you have any information on such calculator/program. Thank you.
