But changing the language in geogebra to translate the commands can be done by every user after he has loaded the file. cheers Werner]]>

But I've implemented it in my file and it works without my understanding :D Perhaps I can use your method to find a solution for the last of those lists: Combination with repetitions. saludos]]>

Wed, 30 Nov 2011 13:12:21 +0000<![CDATA[Hello, @Mathmagik, this is a very clever idea of classification options. Thank you very much! In a very useful new command Zip (In my opinion) there is a problematic place. In this case, L is a one-dimensional list. If VR is a three-dimensional list, L it is logical - two-dimensional list. Are there any restrictions on the dimension of those lists? Roman Chijner]]>

Thu, 01 Dec 2011 09:54:47 +0000<![CDATA[Hi mathmagic, Wonderfull your algorithms! Now I have together all the lists I wanted. But I would like to change your list, so that it can start from every number. (parameter: start). Perhaps you could tell me how I have to change the counters in your formulas. saludos Werner]]>

Thu, 01 Dec 2011 16:45:14 +0000<![CDATA[Hi mathmagic, I mean the first number of the basicset that will be permutated or varied. {1,2,3} start=1 {0,1,2} start= 0 {start,start+1,start+2} Saludos]]>
