For the problem in the Elementary Wolfram Language book (Chapter: Arrays, of Lists of Lists): "Make a grid of all possible strings consisting of pairs of letters of the alphabet (aa, ab, etc.)", an answer could be:
Grid[Table[{Part[Alphabet[], i], Part[Alphabet[], j]}, {i, 26}, {j,26}]]
However, this produces an answer which is a set of lists: {a,a}...and not the preferred: aa... Is there a way to convert a grid of lists to a grid of strings? Thank you.
