The tethrahepton is equal to E100#^^#^#7 = E100#^^#######100 in Extended Cascading-E Notation.[1] The term was coined by Sbiis Saibian.
Etymology[]
The name of this number is based on the number tethrathoth and the root "zetton" from "polyzetton". Polyzetton is the name for a 8-dimensional figure and 8-D figures are constructed from multiple 7-D figures (hence the "poly"), so a "zetton" can be considered a 7-dimensional figure.
