Mission Possible: KenKen Meets BarbieBarbie

Wikipedia on the late Hugh Hefner

“Through his father’s line, Hefner was a descendant of
Plymouth governor William Bradford.  He described
his family as ‘conservative, Midwestern, [and] Methodist’.
His mother had wanted him to become a missionary.”

A quote from Story Space

“Your mission, should you choose to accept it . . . .” —

https://en.wikipedia.org/wiki/Little_Annie_Fanny .

Hefner’s parents might prefer the region of Story Space
proper to Dreamboat  Annie.

New Yorker  video  today, at 14:00-14:25 —

“What’s good about KenKen, and Sudoku, and crosswords,
all of those puzzles like that, is that they have grids to be filled in,
empty squares. I think there is something about human nature
that we want to fill up spaces. And if you’re a puzzle person,
or almost anybody, and you see an empty grid, you want to
put something in those spaces. It gives a feeling of satisfaction
that you don’t get often in life and that really feels good.”

— Will Shortz, New York Times  puzzle editor

“I can’t get no… satisfaction….” — The Rolling Stones

The New Yorker  recently restarted the Weiner story,
which includes —

“… the fall of 2017, when he began a twenty-one-month
prison sentence for sexting with a minor.”

“You want to put something in those spaces.”

— Will Shortz, New York Times  puzzle editor

Yes, you do.

Weiner is now with a Brooklyn countertops company called IceStone.

High School Squares*

Filed under: General,Geometry — Tags: , , — m759 @ 1:20 am

The following is from the weblog of a high school mathematics teacher—

http://www.log24.com/log/pix11/110121-LatinSquares4x4.jpg

This is related to the structure of the figure on the cover of the 1976 monograph Diamond Theory

http://www.log24.com/log/pix11/110122-DiamondTheoryCover.jpg

Each small square pattern on the cover is a Latin square,
with elements that are geometric figures rather than letters or numerals.
All order-four Latin squares are represented.

For a deeper look at the structure of such squares, let the high-school
chart above be labeled with the letters A through X, and apply the
four-color decomposition theorem.  The result is 24 structural diagrams—

Some of the squares are structurally congruent under the group of 8 symmetries of the square.

This can be seen in the following regrouping—
