Hi

I would like ask is how can I actually generate the result as below :

From 4 digits to 3 digits permuted numbers

e.g : 1234 (user enter this)

Generated numbers :

123

124

134

234

…

What we want is use the number posted by user, and we will use the number to arrange to 3 digit numbers in any possible ways as above. Repeated permuted numbers will only display once. Please advise.

Thank you.
