Mathematical Digits are TEN
If "make" is limited to ordering the digits, then 24. If mathematical operations are permitted then several million, at least.

A quadrillion has 16 digits.
There are 90 of them that can be formed by concatenation (writing them side-by-side). You can, of course, form lots more by using mathematical operations. Foe example, 99 = 387,420.489. Combining factorials and powers will give numbers with more than 2 million digits!
6 digits
Twelve in all: One of 4 digits, Three of 3 digits, Four of 2 digits, Three of 1 digit, and One with no digits. In mathematical terms, the last IS a combination, but in common usage, probably not.
If "make" is limited to ordering the digits, then 24. If mathematical operations are permitted then several million, at least.
You can make 24 numbers by rearranging the digits. However, you can make vastly more if you allow mathematical operations on the digits. For example, 3+5*8-6 = 37.

A quadrillion has 16 digits.
Alternate digits refer to the digits in a number that are separated by at least one other digit. For example, in the number 123456, the alternate digits would be 1, 3, and 5 (the first, third, and fifth digits) or 2, 4, and 6 (the second, fourth, and sixth digits). This concept is often used in mathematical problems and patterns to analyze specific sequences or properties of numbers.
