There are 10 combinations of 1 number,
10*9/(2*1) = 45 combinations of 2 numbers,
10*9*8/(3*2*1) = 120 combinations of 3 numbers,
10*9*8*7/(4*3*2*1) = 210 combinations of 4 numbers,
10*9*8*7*6/(5*4*3*2*1) = 252 combinations of 5 numbers,
210 combinations of 6 numbers,
120 combinations of 7 numbers,
45 combinations of 8 numbers,
10 combinations of 9 numbers, and
1 combination of 10 numbers.
All in all, 210 - 1 = 1023 combinations. I have neither the time nor inclination to list them all.

Oh, isn't that just lovely? You can create so many beautiful combinations using the numbers 1 through 9. Just think of all the possibilities waiting to be discovered! Keep exploring and let your imagination run wild with all the different combinations you can come up with.
1,000. The list looks just like the counting numbers from 000 to 999 .
The number of combinations is the number of characters - in this case, 10 - raised to the power if the number of places. So using only the numerals zero through nine, and a 10-character PIN, there are 10 raised to the tenth power combinations, or 1,000,000,000 different possibilities.
It's just a combination of 59 objects chosen five at a time which means (59*58*57*56*55)/(5*4*3*2*1)=5,006,386. Order does not matter in this calculation, which is why it is a combination not a permutation.
There are 17 such numbers.
Assuming that repeated numbers are allowed, the number of possible combinations is given by 40 * 40 * 40 = 64000.If repeated numbers are not allowed, the number of possible combinations is given by 40 * 39 * 38 = 59280.
How many numbers per combination?
Infinite. If numbers can be repeated, the list could go on nonstop.
If you allow digits to be repeated (for example, 222 or 992), then there are 9 x 9 x 9 = 729 combinations. If you do not allow digits to be repeated, then there are 9 x 8 x 7 = 504 combinations.
There is only one combination since the order of the numbers in a combination does not matter.
There are a huge number of combinations of 5 numbers when using the numbers 0 through 10. There are 10 to the 5th power combinations of these numbers.
There is 1 combination of all ten numbers, 10 combinations of one number and of nine numbers, 45 combinations of two or eight numbers, 120 combinations of three or seven numbers, 210 combinations of four or six numbers and 252 combinations of five numbers. That is 1023 = 210 - 1 in total.
Multiple use of a digit.Using the numbers 0 through 9, all the numbers 0000 through 9999 can be made. That's 10,000 (ten thousand) numbers. There are 10 digits (0 through 9), and 10 x 10 x 10 x 10 = 10,000.The list would look like this:0000, 0001, 0002, 0003, 0004, ..., 9995, 9996, 9997, 9998, 9999.Note that this list allows the repeated use of all the numbers. We're taking all the numbers 0 through 9 and creating a replacement set with them to make four-digit numbers.Single use of a digit.If there is a limitation on the repeated use of a number, then the list might appear like this:0123, 0124, 0125, 0126 ..., 9873, 9874, 9875, 9876.In this case, there are 10 x 9 x 8 x 7 = 5040 combinations possible using a non-replacement set of digits (0 through 9) and making 4-digit combinations.

There are 15C3 = 15*14*13/(3*2*1) = 455 combinations, and I am NOT even going to try listing them.
Including the null combination, there are 2^14 = 16384 combinations.
