Combinations and PermutationsI have just finished a rough draft of Combinations and Permutations. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20060712 17:57:32

Re: Combinations and PermutationsThat was fun. I want some ice cream now. #4 20060719 07:37:58
Re: Combinations and Permutations
Thanks, made it: "then alter it so the order does not matter" "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #5 20060728 15:27:40
Re: Combinations and PermutationsPage slightly updated (notation and reference to Pascal's Triangle). "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #6 20060729 16:10:12
Re: Combinations and PermutationsI have been brave and included a "List" facility in the calculator. It took me a while, but I *think* it works correctly. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #7 20111205 17:25:35
Re: Combinations and PermutationsI have been working on a new version! "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #8 20111205 18:20:56
Re: Combinations and PermutationsHi MIF; For the case of repeated elements in the input such as a,a,b,c in which you only draw a few is complicated. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20111205 21:05:09
Re: Combinations and PermutationsEeee ... hadn't thought about that. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #10 20111206 22:52:34
