Hi All I'm looking some better solution for the below list manipulation: l1={a,b,c}; l2={{1,2,3},{4,5,6},{7,8,9}}; output = {{a,1},{a,2},{a,3},{b,4},{b,5},{b,6},{c,7},{c,8},{c,9}} It's a simple distributions of terms. I used this solution, but I think it's not an elegant one: f[a_, b_] := Flatten[{a, #}] & /@ b; MapThread[f, {l1, l2}] // Flatten[#, 1] & Some clue? Maybe with Outer or Inner? Thanks in advance!
