Tethracruxifact

The tethracruxifact (also called hecato-tethracross) is equal to E100(#^^##)^#100 using Extended Cascading-E Notation. The term was coined by Sbiis Saibian.
== Etymology ==
The name "hecato-tethracross" is based on the prefix "hecato-" (meaning 100) and the number "tethracross".
The name "tethracruxifact" is based on the number "tethracross" and the word factor, because #^^# is the only factor of the hyper-product.
