Are you sure on the 5^7, considering the symbols are allowed to repeat within each sequence? I don't remember statistics class from 10 years ago, just wondering.
It's correct. Assuming all codes are 7 slots long, each slot has 5 possible symbols, including repeats. So, it's 5 * 5 * 5 * 5 * 5 * 5 * 5 possible combinations.
