To make whole numbers. The numbers 1,2,4,17,34,68. So 6 numbers.

55----------------------------------------------------------------------------------------------From Rafaelrz.You can make, 5! = 120, five digit numbers using 1,2,3,4 and 6.
Any two numbers such that when 6 is added to the smaller number the sum equals the greater number. For example. 1 and 7 have a difference of 6 as, 1 + 6 = 7 Also, 312 and 318 as 312 + 6 = 318 And you can think of many other pairs of numbers that have this same property.
52C6=(52!)/(6!*(52-6)!)=20,358,520
about... 25 just take 5 numbers times 5 numbers
6 numbers
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.
