Thank you for all the responses. I found them most helpful.

How about if I want to delete repeating cases?  Say I want to be left
with a list of unique pairs from this list
ll={{1, 3}, {1, 4}, {1, 5}, {1, 7}, {1, 8}, {1, 9}, {1, 9}, {1, 9}, {
  1, 9}, {2, 3}, {2, 3}, {2, 5}, {2, 6}, {2, 7}, {3, 5}, {3, 6}, {
  3, 7}, {3, 8}, {3, 9}, {3, 9}, {
  3, 10}, {4, 6}, {4, 8}, {4, 8}, {4, 10}, {5, 7}, {5, 10}, {6, 7},
{6,
    7}, {6, 7}, {6, 7}, {6, 8}, {6, 10}, {7, 8}, {7, 9}, {8, 10}, {8,
10}}

TIA, again.
