comment Block cipher with key longer than block size
but the relation is not established correctly. the factor does not depend on cardinality of block size but cardinality on the set of permutations possible which is the crucial part to be specific

initially LR schemes suggested 4 , patarin proved its not enough and we need atleast 6 to get good security bounds
