Helpsophiaisflirtingmeillion is equal to
10(3*10↑↑103*103*1027,000,000,000,300+3)777,707,070,777(↓↓103*103*1027,000,000,000,300+3-1)+3 using an ill-defined operation ↓↓. It was coined by Trakaplex after what he recalls a "flirting session" with a friend named Sophia, and is intended to be in tier nastihotillion by the creator. It was first clarified on a Googology Testing page without a fixed definition as usual, then a message board post. The number was meant to be part of Bowers' system of illions.
Similar to the original version of Schmittyillion and Inphixillion, the definition includes an ill-defined operation ↓↓. Therefore the number itself has not been formalized yet, and cannot be meaningfully approximated. However, as this illion was said to be in tier nastihotillion, we can informally deduce that the number should be approximately E27,000,000,000,300#3#2.
