Surprise during today's #Bochum (Germany) #sunset - the Sun set right behind the famous #Tetraeder - https://www.tetraeder-bottrop.de - which is 22.3 km away from my vantage point as the crow flies.

Manchmal findet man noch Perlen, die an das "alte Twitter" erinnern.

Triangular and tetrahedral number differences of sumset sizes in additive number theory
The study of sums of finite sets of integers has mostly concentrated on sets with very small sumsets (Freiman's theorem and related work) and on sets with very large sumsets (Sidon sets and $B_h$-sets). This paper considers the full range of sumset sizes of finite sets of integers and an unexpected pattern (related to the triangular and tetrahedral numbers) that appears in the distribution of popular sumset sizes of sets of size 4.

Happy Monday!

Dat in een volgende Tatort een van de bad girls ineens aan de goeie kant staat.

Met een beetje verbazing kijken naar de opening van deze Tatort. Een enkele fietser in een auto doolhof. 😇
Toch is dat maar ruim 10 jaar geleden. (En speciaal vopr de uitzending)
