John Conway developed the LUX algorithm for constructing these things, in which rows of L's, U's and X's are repeatedly interchanged.
John Conway developed the LUX algorithm for constructing these things, in which rows of L's, U's and X's are repeatedly interchanged. A visit to Thailand inspired Simon de la Loubere to create the Siamese method for generating these constructs. These entities are called "satanic" if each of their entries are raised to an integer power and their defining properties still hold. Benjamin Franklin discovered a "semi-" type of these constructs that has order (*) eight and an associated constant equal to 260. In the simplest of these constructs, the number five is at the center and fifteen is the sum of the rows, columns and diagonals. Sudoku was created when amateur mathematicians removed numbers from them. For 10 points, name these grids whose entries sum to a certain value.
