The term Combinatorics refer to object and numbering. From one modul to another modul (combination, combinatorial, permutation, discrete geometry and Algebraic). Currently i am studying the topic of Combinatorial Geometry and how it is influence of structural in architectural design. What i found, some points in Combinatorics refers to the form and shape itself and others are graphs. My research title were Optimising Innovative Modular Design For Affordable Home. So this topics involve in Combinatorial geometry, structural calculation and Algebraic Geometry .
