infinity apeironated (exponentation repeated infinity times) to infinity squared plus tree(3) times mahlo's cardinal times Avogadro's Number times Eddington Number times graham’s number to the power of infinity cubed cubed cubed plus 15 googolplexianthenialarisian to the power of rayo’s number to the power of googolplexianthenialarisian to the power of googolplexianthenialarisian, and then repeat this nesting process an amount of times that equals around twice the value of tree(3)^tree(3)^tree(3)^tree(3)^ tree(3)^tree(3)^tree(3)^tree(3)^ tree(3)^tree(3)^tree(3)^tree(3)^ tree(3)^tree(3)^tree(3)^tree(3)^ tree(3)^tree(3)^tree(3)^tree(3)^ googolplexianthenialarisian squared cubed cubed cubed cubed cubed cubed cubed to the power of utter oblivion (in which I will refer to it as ub) times tree(3)^ub^ub^ub^ub^ub^ub^ub^ub^ub^^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ cubed squared cubed ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub^ub. This is quite beeg but there is still not a “largest number” at all
