# Generate all strings of fixed length from an alphabet [duplicate]

I am trying to create all possible strings of length $8$ from the alphabet $\{+1,-1\}$. I am trying to get help from this question. But not sure where to start from.
• Would this be what you're after, Tuples[{-1, 1}, 8]? – Michael E2 Aug 6 '14 at 18:41
