• Consider sequence of fractions A066657/A066658 produced by ratios of terms in A066720; let m = smallest integer such that all fractions 1/n, 2/n, ..., (n-1)/n have appeared when we reach A066720(m) = k; sequence gives values of k; set a(n) = -1 if some fraction i/n never appears.at n=20A066848
• Aggregate values of n-th stage of growth for two-dimensional cellular automaton defined by "Rule 614", based on the 5-celled von Neumann neighborhood, calculated via even-zeroing instead of mod 2.at n=21A323110
