identical rows in tables

I have a table of values e.g.{{1, 2, 3, 4, 5, 6, 7, 8}, {1, 4, 6, 2, 8, 3, 7, 5}, {1, 4, 2, 6, 3, 8, 5, 7}, {1, 3, 2, 5, 4, 7, 6, 8}, {1, 3, 5, 2, 7, 4, 8, 6}, {1, 2, 4, 3, 6, 5, 8, 7}, {1, 2, 3, 4, 5, 6, 7, 8}} and want to check if any rows are identical (so there are none in the above= - I can remove last or first row which are supposed to be the same). But in the following {{1, 2, 3, 4, 5, 6, 7, 8}, {1, 4, 6, 2, 8, 3, 7, 5}, {= 1, 4, 2, 6, 3, 8, 5, 7}, {1, 3, 2, 5, 4, 7, 6, 8}, {1, 3, 5, 2, 7, 4, 8, 6}, {1, 8, 7, 6, 5, 4, 3, 2}, {1, 8, 6, 7, 4, 5, 2, 3}, {1, 3, 2, 5, 4, 7, 6, 8}, {1, 3, 5, 2, 7, 4, 8, 6},....} there is a pair {1, 3, 2, 5, 4, 7, 6, 8}, {1, 3, 5, 2, 7, 4, 8, 6} which are the same. In an ideal world when I print out (in say TableForm) the repeated rows ca= n be printed in red (or some specified colour) These rows are permutations if that makes any difference. The tables can be= of any size (but always permutations of n numbers) as a subsidiary question is there an easy way to convert the tables into nu= mbers (or strings) eg {12345678,14628375,14263857 etc} Alternatively is there an easy way to perform permutations on strings of ch= aracters? Many thanks for your help to the multiple questions ps I am using Mathematica 6.03
