We can show this mathematically by using the permutations with repetitions formula with n = 3 and r = 2. Our options are: RR, RG, GR, RP, PR, GG, GP, PG and PP. If each time we select a ball we place it back in the bag, how many unique permutations will we have?ĩ different ways. We can see examples of this type in real life in the results of a running race (assuming that two people can't tie for the same place) as we clearly care if we come first and our competitor comes second or if it is the other way around. We can show this mathematically using the permutations formula with n = 3 and r = 2 Our options are: RG, GR, RP, PR, GP and PG. How many unique permutations will we have if we cannot repeat balls?Ħ different ways. Let's say that we wanted to pick 2 balls out of a bag of 3 balls colored red (R), green (G) and purple (P) 1 2 3 Examples of permutations Permutations without repetitions Permutations Calculator What is a permutation?Ī permutation is a selection of r items from a set of n items where the order we pick our items matters. We can see examples of this type of combinations when buying ice cream at an ice cream store since we can select flavors more than once (I could get two, three or even four scoops of chocolate ice cream if I wished) and I don't care about which scoop goes on top (so chocolate on top and vanilla on the bottom is the same to me as vanilla on top with a chocolate base). We can count the number of combinations with repetitions mathematically by using the combinations with repetitions formula where n = 3 and r = 2. Our options are: RR, RG, RP, GG, GP and PP. If each time we select a ball we place it back in the bag, how many unique combinations will we have?Ħ different ways. Let's say that we wanted to pick 2 balls out of a bag of 3 balls, colored red (R), green (G) and purple (P) 1 2 3 We cannot select a team member more than once (so we can't have a team with Danny, Danny and myself) and we do not care about who is selected first to the team (so if I am in a team with Bob and Tom it is the same to me as being in a team with Tom and Bob). We can see examples of this type of combinations when selecting teams for a sports game or for an assignment. We can count the number of combinations without repetition using the nCr formula, where n is 3 and r is 2. How many unique combinations will we have if we cannot repeat balls?ģ different ways. Let's say that we wanted to pick 2 balls out of a bag of 3 balls colored red (R), green (G) and purple (P). Examples of Combinations Combinations without repetitions Thats why you should use empty directories.Combinations Calculator What is a Combination?Ī combination is a selection of r items from a set of n items such that we don't care about the order of selection. NOTE: splitlen does not append, it overwrites the files in the outdir. The best way to organize your dictionaries for use with oclHashcat is to sort each word in your dictionary by its length into specific files, into a specific directory, and then to run oclHashcat in directory mode.Īll you need to do is to create a new directory, for example “ldicts”. OclHashcat has a very specific way of loading dictionaries, unlike CPU hashcat. Note: this optimization is no longer needed by modern hashcat. This program is designed to be a dictionary optimizer for the now-deprecated oclHashcat.
