# b-visibility

- 2026-08-28 [Conjecture] The gasket's `b`-visible density is `(1 - 2^(b-1)/3^b) Prod_{p odd}(1 - p^(-(b+1)))`, not `(8/9)/zeta(b+1)` for every `b >= 1`: the local factor at 2 is `2^(b-1)/3^b`, exact to the integer at `b = 1, 2, 3` on every level `3..12`, and the ratio to `1/zeta(b+1)` is `(1 - 2^(b-1)/3^b)/(1 - 2^(-(b+1)))`, which is `8/9` at `b = 1` (`(2/3)/(3/4)`) and at `b = 2` (`(7/9)/(7/8)`) only - `368/405 = 0.9086420` at `b = 3`, `2336/2511 = 0.9303067` at `b = 4`, climbing to 1; the two formulas part at `b = 3`, `0.8395292` against `0.8212786`, and exact enumeration reads `0.8427119` at level 12, falling about `0.0022` a level toward the former; `b = 1` is the proved `16/(3 Pi^2)`.
