Last evening's Geometry of the Dance discussed
a book on the Norwegian mathematician
Niels Henrik Abel. The post dealt with the group
S4 of 24 permutations of a 4-element set.
"In that open field
If you do not come too close, if you do not come too close,
On a summer midnight, you can hear the music…."
— The dance in Four Quartets
For a summer midnight related to the group S4,
see Midnight in Oslo from last August.
"At the still point…." — T. S. Eliot
"…a dance results." — Marie-Louise von Franz
