Tethrahexon

The tethrahexon is equal to E100#^^#^#6 = E100#^^######100 in Extended Cascading-E Notation. The term was coined by Sbiis Saibian.
==Etymology==
The name of this number is based on the number tethrathoth and the root "ecton" from "polyecton". Polyecton is the name for a 7-dimensional figure and 7-D figures are constructed from multiple 6-D figures (hence the "poly"), so a "ecton" can be considered a 6-dimensional figure.
