The dekaeltertol is equal to E100#^#^#^#^##########100 = E100(#^#^#^#^#^10)100 using Cascading-E Notation. The term was coined by Sbiis Saibian.
The name of this number is based on the prefix "dekael-" (meaning ten hyperions at the top cascade level) and the suffix "-tertol" (meaning cascade level 4).
