Repdigit Numbered Teams

I never though I'd see that day!

The last line of my starting post was in the form of a question, not a conclusion. The question contained a challenge, which Bongle nailed.

And my original post contained no mathematical reasoning; only some bare data, arranged as it might be seen in an advertisement.

For another example that illustrates how sound statistical reasoning trumps sloppy inference from bare data, see the birthday problem. Briefly, given a classroom with N students, what is the probability that two of them have the same birthday? Many a statistics professor has used this one on the first day of a new class. And many a student has been surprised by the result.

My inspiration for the challenge was a stochastic processes professor, long ago, who told our class that "gambling is a tax imposed on those with poor math skills." The highest praise we could get from that professor was "you will be tax-exempt."

Statistics won't predict the future but they will tell you how you should bet. Most of us have a hunch that the form of a team's number shouldn't be predict the team's performance. Bongle's post showed that this is more than a hunch -- it is mathematically defensible.

Playing hunches is reckless. Playing the odds makes you a gamer.

Repdigit numbered teams are not more likely to succeed, but sequential numbered teams are:

45, 67, 234

Oh, maybe that is just because these are from the midwest powerpod and it has nothing to do with sequential numbers ---


If FIRST goes back to a four team game, i hope to be partnered with teams 1, 567 and 890 -

How cool to hear Blair announce 1-234-567-890 !

What about partial repdigit teams--such as 330, 599, or 1197?

Any team in the 1100's or 2200's is sure to be one of those rep teams by default.

Perhaps we have to define a repitition team this way

x = digit a
y = digit b

x (1,4,5,7,8,9)
xx (11,22,33,66,88)
xxx (111,222,333,444,555,888,999)
xxxx (1111,2222)
xyy (100, 122, 133, 144, 155, 166, 177, 188, 211, 233, 244, etc.)
xyxy (1414, 1717, 1818, 2121, etc.)
xyx (101, 121, 131, 141, 151, 161, 171, 181, 191, 202, 242, 252, 262, etc.)


By these definitions, there are a large number of rep-digit teams. It does not always mean that they are successful, but they have interesting numbers that are awesome to look at and read (even if you don't know their names).

how about them prime number teams? how well do they do?

Or xxyy, like ... oh, wait a minute, I'll come up with one.
