Because you were not aware of the polygon's name (to use it as keyword in your searches).
John H. Conway has already named it: HEPTAKAIDECAGON (many authors, however, use the type HEPTADECAGON, which is incorrect)

This construction, when suitably streamlined, has Simplicity 53. The Richmond's (1893) construction of Smith (1920) has a greater Simplicity of 58. Another construction due to Tietze (1965) and reproduced in Hall (1970) has a Simplicity of 50. However, neither Tietze (1965) nor Hall (1970) provides a proof that this construction is correct. Both Richmond's and Tietze's constructions require extensive calculations to prove their validity. De Temple (1991) gives an elegant construction involving the Carlyle Circles which has Geometrography symbol 8S1+4S2+22C1+11C3 and Simplicity 45. The construction problem has now been automated to some extent (Bishop 1978).
