in reply to Re^3: How to restrict partitions
in thread How to restrict partitions

That works to give me the exact number of summands I'm looking for but it give me repeat summands. I get the idea behind the subroutine but I'm not sure how to change it so that it gives only partitions with distinct summands. I tried tinkering with the truth values & the != etc but it didn't seem to do the trick.

    In Perl, "distinct" means "hash": 
    sub distinct {
    my %distinct;
    @distinct{@_} = ();
    return keys %distinct;
}
