Hexagonal tortoise problem
The hexagonal tortoise problem (Korean: Script error: No such module "Lang".; Hanja: Script error: No such module "Lang".; RR: Script error: No such module "lang".) was invented by Korean aristocrat and mathematician Choi Seok-jeong (1646–1715). It is a mathematical problem that involves a hexagonal lattice, like the hexagonal pattern on some tortoises' shells, to the (N) vertices of which must be assigned integers (from 1 to N) in such a way that the sum of all integers at the vertices of each hexagon is the same.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found. The problem has apparent similarities to a magic square although it is a vertex-magic format rather than an edge-magic form or the more typical rows-of-cells form.Lua error in package.lua at line 80: module 'Module:Footnotes/anchor_id_list' not found.
His book, Gusuryak, contains many mathematical discoveries.
