Meameamealokkapoowa oompa

Meameamealokkapoowa oompa is equal to \(\{\{L100,10\}_{10,10}\text{&}L,10\}_{10,10}\) in BEAF, or a meameamealokkapoowa-sized array of L's. John Spencer first asked for the definition of this number.

It is celebrated as the largest googologism Jonathan Bowers has yet defined. It is much smaller than Rayo's number, and is also beaten by Loader's number. The size of this number is controversial, due to not having a proper definition. Some estimates have put it as much larger than outputs of Bird's S function, whilst other analyses put it only slightly larger than the Large Veblen ordinal; less than \(f_{\theta(\Omega^\Omega+\Omega)}(10)\)/
