A triangle with at least two congruent sides. just like our Decimal system has 10 digits. Connect and share knowledge within a single location that is structured and easy to search. Each way of subdividing a tile is called a tile type. R [7] Given a subdivision rule if and only if it is Gromov hyperbolic, it has a sphere at infinity, and the natural subdivision rule on the sphere gives rise to a sequence of tilings that is conformal in the sense above. Subdivision rules were applied by Cannon, Floyd and Parry (2000) to the study of large-scale growth patterns of biological organisms. {\displaystyle s} Overview.
