Pendel
Sally: Die erste und bisher einzige Darstellung eines Pendels,
dessen Abstand größer als Wurzel 2 ist. (2010-6-25)
hpr: Sally, zum einen ist das kein Pendel GRÖSSER als Wurzel 2 (sondern GENAU Wurzel 2), außerdem gibt es noch andere oder größere Pendel: P0574173 , die tollen P0582770 und P0582769 , und sogar mit Turm die P0578192 . Vergleich ist aber wohl nur ok mit anderen Versionen mit mehrschrittigen Figuren, das geb ich zu. (2010-6-25)
