Find repeated rows within each entry of a cell and delete all repetitions

I have a cell that is 255x1, and each entry in the cell is nx3. For all entries of the cell, if a row of values is repeated in the list, I need to delete all appearances of it. Order does not matter (for example, in cell{1,1}, if [45 23 98] and [98 45 23] are present, both of those rows need to be deleted from the list).

Any help with this is appreciated! Thank you!

This oughtta do it:

function C2 = examplecelluniqueage

C = {[1 1 1; 1 7 8; 8 7 1];rand(4,9);magic(2);ones(10)}; %example cell
C2 = cellfun(@removeDups,C,'uni',false); %apply dup remover

function y = removeDups(x)
[uv,~,idxu] = unique(sort(x,2),'rows'); %unique rows of sorted rows
[n,idxh] = histc(idxu,1:numel(uv));     %how many occurences of each row?
idxk = idxu(n(idxh)==1);                %keep the ones that occured once
y = x(idxk,:);                          %extract
