Runs of semiprimes of the same parity {4, 6}, {9}, {10, 14}, {15, 21}, {22}, {25}, {26}, {33}, {34}, {35}, {38}, {39}, {46}, {49, 51, 55, 57}, {58, 62}, {65, 69}, {74}, {77}, {82}, {85}, {86}, {87, 91, 93}, {94},... What are maximal lengths of runs? Up to now I have 7 for even and 82 for odd runs. Thx, Zak.
