Hello,
I hope someone can help me with this.
I have 6 letters (later to be used for a yarn crochet project), but I will only use 5 at the time. Then I use another 5, and another 5 and so on.
I want them all to be unique.
Maybe a routine for the letter A will be enough. I ones followed a Macro and VBA training, and I still can read the most of it, but I miss the skills to really programming.

Thanks very much for helping me

So I have ABCDEF. I made a little beginning on paper, don't think I can finish this that way :-)
Starting with A, is looks like this:
ABCDE
ABCDF
ABCED (note: these are the same as I started with, but they are in a different order)
ABCEF
ABCFD
ABCFE
ABDCE
ABDEF
ABDEC
ABDEF
ABDFC
ABDFE
And so on, and so on.
