It would seem to me that starting from code 0000, 0001, 0002 etc all the way up to 7777 would give me more that 4096 selection possibilities. What am I missing here?
Uhg! Basic math is the short answer.... but that might be unfair.
Each digit can only be set from 0 to 7 giving 8 options.
There are 8 x 8 x 8 x 8 possible combinations = 4096
If these digits could select 0 to 9 then there would be 10 options per digit, and 4 digits gives 10 x 10 x 10 x 10 = 10000 (the expected answer) i.e 0000 through 9999
"Are we there yet?"
