I think I have a simple solution for you using repeated replace l={{{1, 3, 4}, {4, 6, 7}, {{1, 2, 3}, {3, 5}}}, {1, 2, 3}} {l //. {x : {___} ...} -> x} {{1, 3, 4}, {4, 6, 7}, {1, 2, 3}, {3, 5}, {1, 2, 3}} Best regards, PJW dontdont at gmail.com wrote: > Am I overlooking something I should be able to see? > > When I Nest Table I sometimes produce things like this > > {{0, 0, 0}, {{0, 0, 13}, {0, 1, 9}, {0, 2, 5}, {0, 3, 1}}, {{1, 0, 4}, > {1, 1, 0}}} > > where each triple is actually one solution I'm looking for. > But I don't see a simple way to transform this result into > > {{0, 0, 0}, {0, 0, 13}, {0, 1, 9}, {0, 2, 5}, {0, 3, 1}, {1, 0, 4}, {1, > 1, 0}} > > I would have guessed there would be a way to coax Flatten to do this. > > Thus far I haven't found what looks like a good method. > I have found a few awkward and bad ways but no simple clean way. > > Would anyone enlighten me? > > thanks
