Now let's go ahead for the first milestone beyond tethrathoth, namely "grantethrathoth" or "grangol-carta-tethrathoth"! The "carta" root of the latter name comes from Greek for "map". Saibian focuses only on using the "-carta-" operator, but here I am going to use both systems. It is worth noting that the additive connector without the "-carta-" root only works for the pre-tethrathoth roots. Otherwise, the "-carta-" operator is always used for post-tethrathoth roots.
(32075) grantethrathoth / (32076) grangol-carta-tethrathoth ☆★ = E100#^^#100#100
(also (32077) ninety-nine-ex-grand tethrathoth and (32078) tethrathothi-novenonagintiplexitethrathais from the previous regiment)
This expands:
