hello, looking for an easy solution concerning the following issue: i'd like to generate a bunch of numbers, for example 12 in a row using the object (random) for example from 0 to 11 (or another object?). the actual order of the row should be random, the only restriction would be that, after a number appeared, no repetition of that number is allowed until all the other 11 are through... any suggestions? Thanks a lot!

generate series of numbers dodecaphonic style

there's [urn] in zexy, which seems to do what you want.
edit: for vanilla, here's an abstraction, that should do pretty much the same (i hope...)
v.urn.pd -
@steff Here is another approach using text: It takes a number to the inlet and outputs a random list of numbers of this length.
First a list of numbers is generated and stored in [text], then one by one a number is drawn randomly from that urn, the line is deleted from text and added to a list. In the end the list is sent out.

I've heard that the "right" way (with only one operation per output) to do this is to start with an array with values equal to the index. (at 1 =1, at 0 = 0 etc). Then you read a random index, output it, then swap it with the last element of the array. Next time, you choose a random index except for the last, swap it with the second-to-last, and continue decrementing the range of random indices and swapping with the last index that hasn't been swapped yet every time until you reach the beginning of the array.
see c_urn in RjDj for an example in vanilla: https://github.com/rjdj/rjlib/tree/master/rj -
@seb-harmonik.ar Yes, this is basically what @toxonic's and my proposed solutions do
