Let me calculate this number. For calculating of Poincaré recurrence time should use next equation:

$$t_{poincare}=e^{e^{4 \pi \times M^2}}$$ where mass of object $$M$$ and Poincaré recurrence time $$t_{poincare}$$ are expressed in Planck units.

Mass of observable universe is $$10^{61}$$ Planck units.

For observable universe $$t_{poincare}=e^{e^{4 \pi \times 10^{122}}} \approx 10^{10^{5 \times 10^{122}}}$$ Planck units

Observable universe mass multiplied to googolplex $$10^{61}\times 10^{10^{100}}=10^{10^{100}+61} \approx 10^{10^{100}}$$ Planck units

Then Poincaré recurrence time for this mass $$t_{poincare}=e^{e^{4 \pi \times 10^{2 \times 10^{100}}}} \approx 10^{10^{10^{2 \times 10^{100}}}}$$ Planck units

Then Z-2304=$$16 \times 2^{10^{10^{10^{2 \times 10^{100}}}}} \approx 10^{10^{10^{10^{2 \times 10^{100}}}}} \approx $$E100#4.
