I used BigInteger. My methods are different too.

This is the VB Code used to transform from Combination to Index and back.

If the Double data type were a Decimal data type, the code would work for 80/20.

We know VB in Visual Studio will handle the Decimal data type.

The Combinatorial Index works by the Combinatorial Fractalization properties of combinations to determine the Index value directly without having to go through all the preceding combinations to find it.

Right-o about that Excel.

It's unfortunate the VB in Excel doesn't live up to its help.

The help section discusses the data types.

It describes a data type of Decimal; which, if it were actually available in Excel VB, it could handle the extra decimal places beyond 15.

Very interesting... Both of you did something different than I did to end up at the same result.

FYI: Excel (no matter if its 32 or 64 bit) will truncate all numbers over 15 digits.

I ended up using Python- never truncates... built a 2 dimensional array with point values for 20/80 Keno.

For 3 numbers out of 1-10 it looks like this:

N1 N2 N3

1 0 0 0

2 28 7 1

3 49 13 2

4 64 18 3

5 74 22 4

6 80 25 5

7 83 27 6

8 84 28 7

I have created one that can. It is only limited by the speed of the processor and available memory. I will generate the sequence of any size or dimension you want. If you put the numbers you want in a array then run the algorithm It will run as an indexer and and create every possible combination within the given parameters. Generate all 2, 3, 3, 5, etc.\ combinations of the given numbers. So create all 11 million powerball combinations. Break every 5 digit set in to all of the 3, 4, 5 digit com... [ More ]

If you access the code you might be able to port it to a platform, language or machine that can handle more than a 15 decimal place precision.

There are some limitations though that are more to do with your computers ability to handle large numbers.

We used a Double data type that can handle up to 1.79769313486232 10308 , however, it can only goto 15 decimal places on a 32-bit machine.

This would be a problem for a game like Keno 80/20 where there are 3,535,316,142,212,174,320 combinations, but Excel can only handle the first 15 digits and would show as 3,535,316,142,212,180,000.

Yes we have, it's called the Combinatorial Index.

We created an Excel file for converting Combinations into Index Numbers and Index Numbers into Combinations.

or

These are macro enabled.

This is an example of a Pick 6 of 49 conversion you'll see on the first sheet.

Converting a number to a series, and a series to a number.

Datapile — Thu, 01 Jun 2017 23:43:13 GMT

Has any one ever heard of an algorithm that can turn a series of numbers from a set pool/set take into a number, or a number into a series for a given size pool and take?

Pool: 1-10 Take: 3 numbers (120 possible combinations)

ID#1 would be 1-2-3, and ID#120 would be 8,9,10...
