Infinite. If numbers can be repeated, the list could go on nonstop.
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?
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.
To design a counter for a repeated binary sequence, first determine the specific sequence you want to repeat, such as "0101." You can use a finite state machine (FSM) with states representing each bit in the sequence. Each state transition occurs on a clock pulse, cycling through the sequence until it resets. Implement this using flip-flops and combinational logic to ensure the output follows the desired binary pattern.

the equal nukber would be 1000987654 but if you put it that way you will lose the stautus chart and it will mess you up i am a math teacher for 12 grade i know my stuff
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.
DNA contains sequences of nucleotides that encode for proteins through the genetic code. Each protein is made up of a unique sequence of amino acids, which are specified by a specific sequence of nucleotides in the DNA. By using different combinations of the four nucleotides (A, T, C, G), DNA can code for thousands of different proteins.
There is only one combination since the order of the numbers in a combination does not matter.
Assuming digits may not be repeated, there are 10C4 = 10*9*8*7/(4*3*2*1) = 210 of them and I regret that I am not minded to go through the list.
To show congruency between two shapes, you can use a sequence of rigid transformations such as translations, reflections, rotations, or combinations of these transformations. By mapping one shape onto the other through these transformations, you can demonstrate that the corresponding sides and angles of the two shapes are congruent.
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.
