That depends on how many of those six numbers you take.
If you only take one number, there are six combinations: {1}, {2}, {3}, {4}, {5}, and {6}.
If you take two numbers, there are fifteen combinations: {1,2}, {1,3}, {1,4}, {1,5}, {1,6}, {2,3}, {2,4}, {2,5}, {2,6}, {3,4}, {3,5}, {3,6}, {4,5}, {4,6}, and {5,6}.
If you take three numbers, there are twenty combinations.
If you take four numbers, there are fifteen combinations.
If you take five numbers, there are six combinations.
If you take all six numbers, there is only one combination: {1,2,3,4,5,6}.
In general, if you take 'm' objects out of a set of 'n' objects, the number of combinations is given by n!/[(m!)(n-m)!] where '!' is the factorial operator.

No, we don't, unless you tell us more. How many digits are you selecting at a time? Even though you say combinations, I am not sure if you mean arrangements, permutations, or combinations.

### I have a brinks safe that has a combination lock and a key but i cant remember my combination and was wondering how I can reset it. Model number 5059

Each Brinks 5059 safe has a different default combination, so to get the original combination you must either contact Honeywell (the parent company for Brinks safes) at 1-800-223-8566.

You need to send them a notarized letter showing safe ownership in order to get the master combination. When you call Honeywell, you will need to provide your safe's model number, the serial number (found on the right of the safe, near the model number), and your key number.

### How many different number combinations are there using the numbers 1 1 0 8

I assume you mean different decimal numbers, using those four digits, right? If so, the answer can be reached two ways.

One way is to actually build up the model by changing one digit at a time, then moving a decimal place. Thus: 1108, 1101, 1100 then 1118, 1111, 1110 then 1188, 1181, 1180 and so on. You will count 81 combinations.

Since those three different digits can be placed in four decimal places, the answer in another way is: 3*3*3*3=81.

Too many to list (3,125). It would take you forever to get it unlocked. I would suggest bolt cutters and just spend the 20-30 bucks to buy a new one.

There is only one combination using all five digits, namely 1, 2, 3, 4, 7 in some order.

If the order matters then there are 120 different permutations. I won't list them all here, but they start with 1, 2, 3, 4, 7 and go through 7, 4, 3, 2, 1.
