Deutero-tethrahecton is equal to E100(#^^#^100)*(#^^#^100)100 using Extended Cascading-E Notation.[1] The term was coined by Sbiis Saibian. The expression should not to be confused with deutero-tethratope, which is E100#^^#^#*#^^#^#100, which is much larger than this number.

| Bird's array notation | {100,100[1\1\1\1...1\1\1\2]1[1\1\1\1...1\1\1\2]2} (where there are 100 1's) |
| Fast-growing hierarchy | \(f_{\varphi(100,0)^2}(100)\) \(= f_{\omega^{\varphi(100,0) \times 2}}(100)\) |
