Dependence of the effective triggering rate <i>R</i>_eff on the system size <i>N</i> for a fixed spontaneous triggering probability <i>q</i> = 0.01.

<p>1D corresponds to a 1 × <i>N</i> array, 2D corresponds to a <math><mrow><msqrt><mi>N</mi></msqrt><mo>×</mo><msqrt><mi>N</mi></msqrt></mrow></math> array of hexagonal cells. The inset shows the dependence of <i>R</i>_eff on <i>q</i> for a fixed number of cells <i>N</i> = 100.
