END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

A Matchmaker Julia set with two period-3 attractors. There is a Julia set with a = 0 that is like Interlock II, only with three rather than two petals per basin, interleaved. The basins are exactly symmetrical when a = 0. Here, with a not zero, the interlock pattern is still apparent, but the basins are not symmetrical: one is fat, the other narrower and crenellated, because for the other basin we're closer to the bud boundary in the 4-D M-set.
