Summary
DescriptionSupersilver Rauzy aba.png
English: The production rule is (a ↦ aba) (b ↦ c) (c ↦ a) with initiator b, iterated for 20 generations. The incidence matrix M [2,0,1; 1,0,0; 0,1,0] has characteristic polynomial f(x) = x3 − 2x2 − 1 and dominant eigenvalue ς = 2.20557 (the supersilver ratio). The central tile and its three subtiles have areas in the ratios ς4 − ς3 − ς2 : ς2 : ς : 1. The viewport height is 2.6 and the origin is at the cross.
