They were supposedly related to a geothermal study.

hello friends. by chance do you know what are those little modules for? 
edge length is about 15 cm.
from one day to the next there were literally thousands of them along all streets and roads in parts of Geneva and on the French side of the border.
they are spaced about 20m aparts.
they left them there about for 2 weeks, and took them all away at once just as quickly as they disposed them.
they also put some in private properties, e,g, the one on the picture is one of the 4 they position in the foreyard of our little building.

It acknowledge this is a question that best fits in the Honesty Test thread but I will ask it here.
kata, were you sincerely willing to help me out with this answer?

I think I, subconsciously, which may indicate utmost sincerity, wanted to joke.
Consciously, I was being spontaneous! What? ^o.0^
Suppconsviously, I was sincerely trying to help.
Well, dextroconsciously and levoconsciously I was isomeric at best.
Looking forward(-consciously) to my test result!

Reminds me of the classic Ken Dodd joke:

"The man who invented cats' eyes got the idea when he saw the eyes of a cat in his headlights. If the cat had been going the other way, he would have invented the pencil sharpener."

hello friends, and once again happy new year.
what is (the name of) a simple yet efficient algorithm/method to enumerate all the combinations of k elements in a set of with a total of n elements?
in my use case this will be all combinations of 2 elements among  ~1K elements..
apologies if this is a dumb question.

K-means clustering.

And if you were just joking, Ha ha.

But if serious - some useful guidance here: https://reference.wolfram.com/language/ ... Means.html

hello Trackstar. No no I was not joking.
I mean on the internet I didn't found any clear definition / name.
I'm looking at the Wolfram page you suggest now.
Many thanks.

n (n-1)/2

Generally: [$]n \choose k[$]

yes, thank you Alan. i was searching an efficent logics to spit out all those combinations. I assumed such "algorithms" bear a name.
for now, i'm lazily hanging around pyrhon itertools.combinations(iterable, r)

Why?? Just import math: math.comb(n,k)
