Labs septic
From Wikipedia, the free encyclopedia
Template:Short description In mathematics, the Labs septic surface is a degree-7 (septic) nodal surface with 99 nodes found by Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.. As of 2015, it has the largest known number of nodes of a degree-7 surface, though this number is still less than the best known upper bound of 104 nodes given by Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found..[1]
