Very interesting this update, for fun I did the test with a precalculation of the points on #75 bit with -max 3 this already requires 350 Mo of free space.
how many Go available requires for example the precalculation of a 100bit space with -max 10 ?
I did a 85bit -max10 the Generation took 4 hours and 35GB of space
ok thank you for your answer I'm going to test a 90 in -max 5 to see but I'm not sure I'll have enough space we'll see
