generate all 7-letter formations, maximum 3 letters repeated.
ex = aaabcde ... bbbcccd, etc.
we have 10 letters = abcdefghij to conbine the formations with 7 letters
please!

pgc01 · Oct 6, 2018

Not relevant now, but just out of curiosity,

another way to calculate the total number of combinations: all the combinations minus the combinations with 4 repeated elements:

=COMBINA(10,7)-10*COMBINA(10,3)

=9240

piter · Oct 6, 2018

ok PGC01, correct!!! thank you!

shg · Oct 6, 2018

COMBINA -- a multi-choose function. That was a nice addition (I use 2010).

=COMBIN(10 + 7 - 1, 7) - 10 * COMBIN(10 + 3 - 1, 3)

I just noticed that there are several patterns that have NEVER come out in the 20 year history of the UK Lotto. Not to say they won't ever appear, but these combos are seriouslyunlikely!

You realize those are not equally likely?

Here's is the frequency of those patterns for 49 choose 6, and the expected number of appearances in 7300 draws (daily for 20 years):

The yellow ones are those you haven't seen; not surprisingly, they are among least likely. And conversely, the most frequent appearing are among the most likely.

Your Lotto looks comfortingly random.

COMBINA -- a multi-choose function. That was a nice addition (I use 2010).

I didn't know either. I checked which were the new functions for 2013 but I missed this one.
It was just when I started to write the formula and intellisence showed this new option that I realised that it existed.

IMO, these functions were lacking. If you had functions for combinations and permutations without repetition, it makes sense to have the same functions for the case of repetition.

Interesting how they built the names of the new functions differently for the 2 cases

COMBIN() - COMBINA()
PERMUT() - PERMUTATIONA()

For the front end triple, only 16 combinations make up 95% of the winning combinations. These are (listed by number of hits):
AAB, ABB, ABC, AAC, AAA, BBC, ACC, BCC, BBB, ACD, BCD, ABD, AAD, CCC, CCD and BBD

And, for the back-end triple only 15 combinations are used 95% of the time:
DEE, DDE, CDE, EEE, CDD, CEE, CCD, CCE, DDD, BCE, BDE, BCD, BDD, CCC and BBD.

As you should expect:
