The numbers: {1, 2, 4, 12, 14, 21, 24, 41, 42, 124, 142, 214, 241, 412, 421}.
If repeats are allowed, the above plus: {11, 22, 44, 111, 222, 444} plus infinitely many more by preceding the numbers given so far by various combinations of {1, 2, 4} in 1, 2, 3, ... digit groups making 4, 5, 6, ... digit numbers.

How many binary numbers can be written using seven digits?
A binary number consists of two possible digits: 0 and 1. When using seven digits, each digit can independently be either 0 or 1. Therefore, the total number of binary numbers that can be formed with seven digits is (2^7), which equals 128. Thus, there are 128 different binary numbers that can be written using seven digits.

How many four digits numbers can be made with 1 4 5 9 without repetition?
To calculate the number of four-digit numbers that can be made using the digits 1, 4, 5, and 9 without repetition, we use the permutation formula. Since there are 4 digits to choose from for the first digit, 3 for the second, 2 for the third, and 1 for the fourth, the total number of permutations is 4 x 3 x 2 x 1 = 24. Therefore, there are 24 different four-digit numbers that can be formed using the digits 1, 4, 5, and 9 without repetition.
How many numbers can you make from 650271 without repeating a digit?
1,956 different numbers can be made from 6 digits. You can calculate this by using the permutation function in a summation function, like this: Σ6k=1 6Pk = 6P1+6P2+...+6P5+6P6 What this does is calculate how many 1 digit numbers you can make from 6 digits, then how many 2 digit numbers can be made from 6 digits and adds the amounts together, then calculates how many 3 digit numbers can be made and adds that on as well etc.
