The Twist Operator on Maniplexes, to higher dimensions. Since the twist on a maniplex preserves all the orientation preserving symmetries of the original maniplex, we apply the operation to reflexible maniplexes, to attack the problem of finding chiral polytopes in higher dimensions.作者: 傾聽 時(shí)間: 2025-3-22 03:09
,Pascal’s Triangle of Configurations,. As an interesting consequence, we show that all these configurations are connected to incidence theorems, like in the classical case of Desargues. We also show that these configurations can be represented not only by points and lines, but points and circles, too.作者: 一大群 時(shí)間: 2025-3-22 06:27 作者: 尖叫 時(shí)間: 2025-3-22 09:55 作者: Aids209 時(shí)間: 2025-3-22 15:17 作者: Aids209 時(shí)間: 2025-3-22 20:45
