The tmf-ASS differentials conjecture for ZZ, part 2

In the tmf\mathrm{tmf}-Adams spectral sequence for ZZ, let ϵj,ϵˉj{0,1}\epsilon_j,\bar\epsilon_j\in\{0,1\} and let m0m\gg0. Differentials conjecture, part 2. The v2v_2-families

v2mh~2,1ϵ1h3,0ϵ2h3,1ϵ3h~4,1v_2^m\widetilde h_{2,1}^{\epsilon_1}h_{3,0}^{\epsilon_2}h_{3,1}^{\epsilon_3}\widetilde h_{4,1}

support differentials hitting the v2v_2-parabolas supported by

h~2,1ϵ1h3,0ϵ2h3,1ϵ3x32.\widetilde h_{2,1}^{\epsilon_1}h_{3,0}^{\epsilon_2}h_{3,1}^{\epsilon_3}x_3^2.

Also, the v2v_2-parabolas supported by

h~2,1ϵ1h3,0ϵ2h3,1ϵ3h~4,1x3k3x4ϵˉ4x5ϵˉ5\widetilde h_{2,1}^{\epsilon_1}h_{3,0}^{\epsilon_2}h_{3,1}^{\epsilon_3}\widetilde h_{4,1}x_3^{k_3}x_4^{\bar\epsilon_4}x_5^{\bar\epsilon_5}\cdots

support differentials hitting the parabolas

h~2,1ϵ1h3,0ϵ2h3,1ϵ3x3k3+2x4ϵˉ4x5ϵˉ5.\widetilde h_{2,1}^{\epsilon_1}h_{3,0}^{\epsilon_2}h_{3,1}^{\epsilon_3}x_3^{k_3+2}x_4^{\bar\epsilon_4}x_5^{\bar\epsilon_5}\cdots.

The conjecture extends the earlier differentials conjecture by including the d4(h4,1)=v2x32d_4(h_{4,1})=v_2x_3^2 pattern; the existence and nontriviality of these differentials are open.
