I'm hoping this is really simple, but I can't just seem to get it!
I have an 8 character code that consists of 3 letters [A] and 5 numbers [N]
I need to work out the possible positional/ordering combinations of those 8 characters, e.g. ANNANNNA, AANANNNN, NNNAAANN etc...
Please note I'm not concerned with the total number of possible codes (which hopefully is $26*26*26*10*10*10*10*10$ ), just the ordering combinations.
Many thanks in advance, and apologies for any bad usage of terms!
