this output is the intersection of pairs of larger subsets:

{{13, 24, 68, 79}, {13, 24, 68, 79, 90}, {13, 24, 44, 48, 68, 79}, {13, 20, 44, 48, 68, 79}, {13, 24, 44, 55, 68, 79, 90}, {13, 24, 44, 68, 79}, {13, 20, 24, 44, 48, 55, 79}, {13, 20, 44, 55, 68, 79}, {13, 20, 44, 68, 79}, {13, 24, 48, 68, 79, 90}, {13, 24, 48, 68, 79}, {13, 24, 48, 55, 79, 90}, {20, 24, 44, 68, 90}, {13, 24, 79, 90}, {13, 20, 48, 68}, {20, 68, 79, 90}, {13, 20, 68}, {20, 24, 68}, {20, 68, 79}, {20, 24, 79}, {13, 20, 24}, {20, 24, 68, 90}, {24, 44, 68, 79}, {13, 24, 68}, {20, 24, 44, 79}, {13, 20, 44, 55, 79}, {13, 20, 79} …

now I would like to eliminate the intersections that are already present in other intersections, for example:

{13, 24, 68, 79} is already present in {13, 24, 68, 79, 90} and {13, 24, 44, 48, 68, 79}

{13, 24, 68, 79, 90} is already present in {13, 24, 44, 55, 68, 79, 90} …

how to do?

thanks
