I created with
Tuples[{{USD, EUR, JPY}, {UP, DOWN}}]
the following result:
{{USD, UP}, {USD, DOWN}, {EUR, UP}, {EUR, DOWN}, {JPY, UP}, {JPY, DOWN}}
I want to further have a 3 dimensional list of all combinations - but the same currency does not appear twice. Example output
{{{USD, UP}, {EUR, UP}, {JPY, UP}},
{{USD, UP}, {EUR, UP}, {JPY, DOWN}},
{{USD, UP}, {EUR, DOWN}, {JPY, UP}},
{{USD, UP}, {EUR, DOWN}, {JPY, DOWN}},
...
{{USD, DOWN}, {EUR, DOWN}, {JPY, DOWN}}}
Is there a simple way to do it?
