There are 46C5 = 46*45*44*43*42/(5/4/3/2/1) = 1,370,754 of them and I am not stupid enough to try and list them. You are welcome to try, though.
There are twelve possible solutions using the rule you stated.
120 different combinations (5 x 4 x 3 x 2).

There are 35C4 = 35*34*33*32/(4*3*2*1) = 52,360 combinations.
There are only five combinations: 1234, 1235, 1245, 1345 and 2345.
The number of combinations, denoted by 11C6 is 11!/[6!*(11-6)!] = 11*10*9*8*7/(5*4*3*2*1) = 462

From 1 to 20, you can pull out 15,504 different groups of 5 numbers, and each group can be lined up in 120 different orders.
Including the leading zero, then the answer is 210. Or, allowing for repeating numbers, 10000.

Decimal numbers that never end but that end up having a repeating pattern are called recurring decimals or repeating decimals.Examples would be 1/3 = 0.33333333...or 452/555 = 0.8144144144144144... (where 144 is the repeating pattern).Reaching that repeating pattern is known as becoming periodic. Only rational numbers will have a repeating pattern. (The repeating pattern may be 00000, as in 4/2 = 2.00000... .)If a decimal number continues forever without having a repeating pattern, then it is a irrational number. One example of a number that continues forever without repeating would be π (pi) which continues infinitely without repeating.Pi is also referred to as a transcendental number.
You can make 5 combinations of 1 number, 10 combinations of 2 numbers, 10 combinations of 3 numbers, 5 combinations of 4 numbers, and 1 combinations of 5 number. 31 in all.
