At least one of the key biologically-inspired experiments using HTM algorithms seems to produce [reasonable results](https://discourse.numenta.org/t/untangling-sequences-revisited/6295) when run with 100 minicolumns per cortical column. (See further down that thread, and also [this earlier thread](https://discourse.numenta.org/t/untangling-sequences-behavior-vs-external-causes/2883), for reference to the Numenta paper, and description of the HTM-scheme implementation of the experiment: it was originally run with the Numenta SDR configuration of 20 ‘on’ bits in 1024, but can produce comparable output with 4/100.)
