Tethradekon

The tethradekon is equal to E100#^^#^#10 = 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 "dakon" from "polydakon". Polydakon is the name for a 11-dimensional figure and 11-D figures are constructed from multiple 10-D figures (hence the "poly"), so a "dakon" can be considered a 10-dimensional figure.
