While perusing the 'Never Ending Book' Site, I came across this link to the Terry Gannon ArXiv paper 'Monstrous Moonshine: the first 25 years'. http://www.arxiv.org/PS_cache/math/pdf/0402/0402345.pdf Lieven le Bruyn refers to this as a survey paper [33 pages with 124 references]. It appears to form the framework of the Gannon book, ‘Moonshine Beyond the Monster’ [477 pages, 575 references]. Gannon comprises a masterful effort relating modular forms, E8 and the Leech Lattice to the Monster and VOA for the complex-24D. He explains the Cartan-like structure of Borcherds-Kac-Moody algebras. He touches upon the concept of imaginary time for D26. He does not appear to discuss the string-25D. He relates Mathieu groups and the bi-monster as "mini-monster" and "maxi-monster", respectively, but does not address their apparent relation to Golay codes.
